Q1:

In the circuit of figure, the current through battery E3 is

A 4 A charging

B 4 A discharging

C 4 A charging or discharging depending on value of E3

D 4 A charging or discharging depending on values of E1, E2, E3

ANS:A - 4 A charging

4 A current is flowing into the battery. Therefore, it is charging current.
