Jun 24	comment	Why is power supply from electrical utility referenced to earth? Why doesn't the breaker blow without ground reference? Also why is return path necessary fro current to flow? I thought if there was a potential difference current would flw.

Jun 17	comment	What happens if an AC voltage is applied to a battery? A Resistor could also be used to drop the voltage right? What advantage would a diode provide over a resistor?
Jun 15	comment	What happens if an AC voltage is applied to a battery? Thanks for the answer. Does all rectifier's has a AC component? Because when I have used my multimeter for similar charing circuits I haven't detected AC before.Also what would happen if an AC voltage is directly used to charge a battery without using a rectifier ?
