The____________wire is connected to the negative terminal of the mains supply.
Hence, The neutral wire is connected to the negative terminal of the mains supply.
A 5.0 μF capacitor is charged to 12 V. The positive plate of this capacitor is now connected to the negative terminal is now connected to the negative terminal of a 12 V batter and vice versa. Calculate the heat developed in the connecting wires.
a storage battery is to be charged from a dc supply. should the negative or positive terminal of battery be connected to positive side of it
