Question
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
Options
A.Potential difference across points A and B must be more than E
B.Potential difference across points A and B must be more than E
C.In battery, current flows from positive terminal to the negative terminal
D.No current flows through battery
Solution
ᐃV = E + ir and in charging current flows from positive terminal to negative terminal.
