The positive and negative poles of the data line are inserted in reverse
If the positive and negative poles of the data lines were inserted in the opposite direction, many situations could occur. First of all, it might not show that it was charging, and it would cause great damage to the phone. If maintenance was needed, it might cost more. One solution was to change the chip, but the labor cost was too high. The other was to short circuit the tail plug with the battery compartment contact to charge the battery and cut off the detection resistance. However, in this case, you could also consider buying a universal charger and a backup battery. In addition, if it showed that it was charging, it meant that it was connected correctly and could be used without worry. It could also be a production error that caused the positive and negative poles to be inserted in the opposite direction, such as a worker's welding error, or a lack of quality inspection when the economy was not good and the labor cost was reduced.

Will the charger break if the positive and negative poles are connected in reverse? How to repair it?
Whether the positive and negative poles of the charger were connected in the opposite direction would be damaged and how to repair it depended on the type of charger. Take the electric car charger as an example: - If the positive and negative poles of the battery car charger are connected in reverse, it may cause damage to the charger's charging capacity. At this time, the charger can be repaired by replacing the charging capacity. The general maintenance steps included unplugged the charger, checking the charger's plug, the electric vehicle charging socket, and the electric vehicle's fuse. After reinserting the normal plug, it began to charge normally. - If the positive and negative connections were broken, it was generally necessary to check the secondary circuit of the switching transformer in the charger, the rectify circuit, the output conversion tube, and also check whether the output current limiting resistance was open. The output wire to the plug also needed to be tested. When the positive and negative stages of the 48V green source charger are connected in reverse, it may cause R27 to burn out and LM358 to breakdown. The phenomenon is that the red light is always on, the green light is not on, and the output voltage is low or close to 0V. It can be repaired by replacing the above components. In addition, if the output of the charger has special functions such as anti-reverse connection and anti-short circuit (such as adding an additional relay at the output, the relay will not work when reverse connection or short circuit occurs, and the charger has no voltage output), it is also necessary to check the relay and other related components. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What if the positive and negative poles of the generator slip ring are connected in reverse?
Aiya, if the positive and negative poles of the generator slip ring were connected in reverse, he couldn't just leave it alone. First of all, he had to quickly cut off the power supply. He couldn't let it continue to work in the case of a wrong connection. Otherwise, it might cause a lot of trouble, such as damaging the equipment. After that, he had to carefully re-connect the positive and negative poles. If he wasn't sure what to do, it would be best to find an experienced technician to deal with it. After all, they were professional and could guarantee that the matter would be resolved safely and correctly. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The positive and negative poles of the equipment are connected in reverse and will explode immediately. What is it that is broken?
Why can't the positive and negative poles of a direct current capacity be connected in reverse?
Where will the positive and negative poles of the charger burn?
If the positive and negative poles of the charger were reversed, the resistance of the charger and the electronic components of the power supply might be burned. When the charging connection was reversed, there would be a large current flowing through the battery and the charger. Because the current was too high, the battery would heat up violently, causing the plate to swell and be damaged. The active material would fall off, reducing the power storage and service life. The charger might have a situation such as burning the high-power resistance surface at the output end. For a battery charger with anti-reverse connection function, if the positive and negative poles were connected in reverse, there would be no voltage output. In this case, the charger itself might not burn the components, but it would not work normally. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The positive and negative poles of the electric car charger are reversed
When the positive and negative poles of the electric car charger were reversed, it would not explode, but it would burn the charger's rectify component and high-frequency transformer. Because the voltage of the battery and the charger were added during charging, the current would flow into the charger in the opposite direction and would not be controlled by the circuit, which might burn the charger. If the charger fuse is not broken, if the output part of the copper foil is blown after opening the charger (this situation is usually caused by the positive and negative poles), it may return to normal after connecting the broken copper foil and replacing the damaged components. There were also cases where the E-shaped circuit was burned, and it could be repaired by reconnecting it (this method was shared by non-professionals). In addition, a short period of negative and positive reverse connection may not have much effect on the battery, but it will burn the battery over time. The degree of battery damage is directly proportional to the length of reverse connection. If the battery is charged in reverse, it is equivalent to a short circuit, and the battery may burn or explode. When using, try to use the original charger or the same model to avoid the occurrence of the positive and negative pole connection. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The positive and negative poles of the camera's charging battery
Different brands of camera batteries had different positive and negative labels. For example, Lingye camera batteries had positive and negative labels; Canon original batteries did not have positive and negative labels; Green Giant Rechargeable camera batteries had positive and negative contacts in the slot and positive and negative labels beside them. In the case of a camera charger connected to a camera, the positive and negative poles were not on the side of the camera or charger alone. Nowadays, it was mostly a wire or plug type, usually with the positive pole inside and the negative pole outside. In addition, in the charging flashlight, the red power cord was connected to the positive battery, which could be used as a reference, but the connection of the camera battery needed to be determined according to the specific product. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
How to Look at the Positive and Negative Poles of the Voltmeter and Ampere Meter
Generally, the zero line of an ammeter or a voltage meter was on the left side, and the pointer was tilted to the right when it was energized. If the positive and negative terminal of the voltage meter or ammeter were connected in the opposite direction, the pointer would deflect in the opposite direction. This situation was more obvious in the direct current meter, but the alternating current meter did not have a positive and negative pole, so there was no such problem. In severe cases, it was easy to burn the meter if the positive and negative poles were connected in reverse. If the meter was damaged, it might affect the circuit. For example, in some circuits, if the voltage meter or ammeter was damaged, it would affect the measurement results or the normal operation of the circuit. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Will the negative and positive poles of the cell phone battery burn the screen?
The negative and positive poles of the phone battery might cause the current to be abnormal, which would trigger the battery protection mechanism. The phone would automatically enter the white screen state for safety, but this did not mean that the screen was burnt. There were also opinions that modern mobile phones had reverse phase protection, so the battery would not burn the phone parts because of the positive and negative poles, but the phone might not be able to turn on. However, there was no clear indication that the battery's positive and negative poles would directly burn the screen. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
