6. Excessive Current Draw. Another major reason for battery leaks is an excessive current draw. A swollen battery is the result of excessive current being drawn from it. Because of the expansion, the container may break, letting the electrolytes escape. The outcome is a damaged battery and a possible risk of fire.
Reverse leakage current
Reverse leakage current in a semiconductor device is the current when the device is reverse biased. Under reverse bias, an ideal semiconductor device should not conduct any current, however, due to attraction of dissimilar charges, the positive side of the voltage source draws free electrons (majority carriers in the n-region) away from the P-N junction. The flow of these electrons results …
