Does the barrier capacity increase with the reverse voltage?
The barrier capacity decreased as the reverse voltage increased, not increased. When a reverse voltage was applied to both ends of the junction, the junction became wider, and the amount of space charge in the junction increased, which was equivalent to the " charging " of the junction. The difference between a barrier and a normal one was that its capacity was not constant, but was related to the applied voltage. When the applied reverse voltage increased, the barrier capacity decreased, and when the reverse voltage decreased, the barrier capacity increased. Read more exciting novels for free
Reverse voltage multiplication
There were several ways to achieve inverse voltage multiplication: 1. The input voltage was raised using a transformer, and then converted to a reverse voltage through a rectify circuit. 2. Using a voltage doubler circuit, the voltage was increased by connecting multiple reactors in series. 3. A voltage doubler circuit was used to increase the voltage through a multi-stage rectify and filter. 4. Using a voltage amplifier to amplify the input signal to increase the reverse voltage, the negative feedback method can be used to connect the amplifier circuit to obtain the reverse proportional voltage. In addition, there are also chip TC682IOA, TC682COA inverted voltage multiplying IC chips that can be used in related circuits. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Why does the reverse connection of the voltage meter not change? The negative current becomes smaller.
The internal resistance of the voltage meter is very large. It should be connected in parallel in the circuit during normal use. When the voltage meter was connected in reverse, it was connected in series in the circuit. Due to its huge internal resistance, according to Ohm's law (I = U/R), under a certain voltage, the resistance would increase and the current would become extremely small. The working principle of the voltage meter was based on electrical principles such as electromagnetic induction. It measured voltage, not current. The internal structure of the voltage meter determined that its reading would not be negative (ordinary voltage meters did not have reverse scales to display negative values). Therefore, the current would become smaller and the reading of the voltage meter would not become negative. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Why can't the positive and negative poles of a direct current capacity be connected in reverse?
The ammeter didn't show the number, and the voltage meter was connected in reverse. What's going on?
The reverse connection of the voltage meter belongs to the wrong connection of the voltage meter. The voltage meter needed to be connected in parallel in the circuit with the positive and negative poles connected correctly. If the positive and negative poles of the voltage meter were connected in reverse, the voltage meter would not be able to measure the voltage normally. However, the absence of an ammeter could be caused by many reasons, such as an internal fault of the ammeter.(Internal coil, pointer, resistance and other components may malfunction due to long-term use, environmental factors, etc.), improper selection of ammeter range (The measured current value exceeds the range of the ammeter), ammeter connection error (such as connecting the ammeter in parallel in the circuit or connecting the positive and negative poles of the ammeter in reverse), circuit failure (open circuit, short circuit, etc. in the circuit), ammeter damage (it may be damaged due to external forces, high temperature, etc.), etc. However, based on the information given, it cannot be determined that the ammeter has no indication and the voltage meter is connected in reverse. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Cause of single-phase voltage fluctuation in low-voltage line
Based on context alone The single-phase voltage fluctuation of low-voltage lines mainly has the following reasons: ** 1. Power Source Side ** 1. ** The generator output is unstable ** - The speed fluctuation of the generator will affect the frequency and magnitude of the output voltage. For example, when the speed governing system of the generator's prime motor (such as a steam turbine or a water turbine) fails, the speed may change. If the rotation speed increases, according to the formula [E = 4.44fN 'Phi]([E] is the induced EMF,[f] is the frequency,[N] is the number of coil turns, and [Phi] is the magnetic flux), the frequency [f] increases, and the induced EMF [E] also increases, causing the output voltage to fluctuate. 2. ** Transformer problem ** - The tap setting of the transformer was unreasonable. If the tap position of the transformer was not selected properly, for example, when the voltage needed to be increased, the tap was set to the step-down position, which would cause the output voltage to deviate from the rated value and cause voltage fluctuations. - Transformer malfunction. If the winding was short-circuited, it would change the equivalent induction and resistance of the transformer, thus affecting the voltage output. After a turn-to-turn short circuit, the short-circuit winding's inductivity will decrease. According to U = L_frac{di}{dt}_(U_is the voltage, L_is the inductivity, I_is the current, and t_is the time), the voltage will decrease under the condition that the current rate of change is constant. Due to the unstable state of the short-circuit fault, the voltage will fluctuate. ** 2. Load-side factor ** 1. ** Connection and removal of high-power single-phase load ** - When high-power single-phase equipment (such as large welding machines, single-phase electric furnaces, etc.) suddenly connected to the low-voltage line, it would cause a sudden increase in the line current. According to the value of U = IG (U = IG)(U = voltage, I = current, and R = line resistance), the voltage drop on the line will increase, causing the voltage at the load to decrease. When these devices were suddenly removed, the current would decrease rapidly, and the voltage would rise again, causing voltage fluctuations. 2. ** Unbalanced load ** - In a three-phase four-wire low-voltage system, if the three-phase load was seriously unbalanced, there would be a current flowing through the neutral wire. When there is resistance in the neutral line, there will be a voltage drop of U_N = I_NRN (U_N is the neutral line voltage drop, I_N is the neutral line current, and R_N is the neutral line resistance), which will cause the single-phase voltage to fluctuate. For example, if a certain phase is overloaded, the voltage of that phase will decrease, and the voltage of the light-loaded phase will increase. ** 3. Route factor ** 1. ** Line Resistance ** - The aging of the line or the small diameter of the line will increase the resistance of the line. When the load current passes through, according to U = IG, a large voltage drop will occur. As the load current changed, the voltage drop would also change, causing voltage fluctuations. 2. ** Line inductivity and capacity ** - Long-distance low-voltage lines had the effect of inductance and capacity. When the current in the circuit changed, the inductors would generate an induced electromagnetic force to hinder the change in the current, and the condensers would charge and discharge. These processes would cause fluctuations in the line voltage. For example, in some rural long-distance low-voltage power supply lines, the influence of this kind of inductance and capacity may be more obvious. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

What's the difference between battery voltage and cell voltage?
The battery voltage refers to the voltage of the entire battery, while the cell voltage refers to the voltage of the individual battery cells that make up the battery. For a battery consisting of multiple cells in series (such as a lead-acid battery consisting of N 12V cells in series), the battery voltage is the total voltage after the cell voltage is combined in series. For example, 16 strings of 48 volts of iron lithium, 16 units in series, and the corresponding voltage of each unit together constituted the 48 volts of the entire battery. Different charging and discharge conditions affect the cell voltage, which in turn affects the battery voltage. The difference in cell voltage will also have different effects on the battery's performance and life. For example, the greater the difference in cell voltage, the shorter the battery's life. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Normal battery voltage
For camera batteries, the general nominal voltage was 7.2V, and the discharge and full voltage range was about 7.4 - 8.4V, which could be as wide as 7.2 - 8.4V. However, there were also cases where the battery voltage was 3.6V. For example, the battery voltage of the Canon BG- 718 was 3.6V. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
