A storage battery is to be charged from a D.C. supply. Should the positive or the negative terminal of the battery be connected to the positive side of the line? Explain.

Which metal is connected to the negative terminal of the battery?

In order to forward bias a PN junction, the negative terminal of battery is connected to

Which metal is connected to the positive terminal of the battery?

A battery is of emf E is being charged from a charger such that positive terminal of the battery is connected to terminal A of charger and negative terminal of the battery is connected to terminal B of charger. The internal resistance of the battery is r .

................. is connected to the negative terminal of battery.

A capacitor of capacitance C which is initially charged up to a potential differnce epsilon is connected with a battery of emf epsilon such that the positive terminal of the battery is connected with the positive plate of the capacitor. Find the heat loss in the circuit the process of charging.

A capacitor of capacitance C which is initially charged up to a potential differnce epsilon is connected with a battery of emf epsilon/2 such that the positive terminal of the battery is connected with the positive plate of the capacitor. Find the heat loss in the circuit the process of charging.
