Question

In the adjoining diagram, the condenser `C` will be fully charged to potential `V` if
.
A. `S_(1)` and `S_(2)` both are open
B. `S_(1)` and `S_(2)` both are closed
C. `S_(1)` is closed and `S_(2)` is open
D. `S_(1)` is open and `S_(2)` is closed.

Answer 1

Correct Answer - C
If `S_(1)` and `S_(2)` both are closed then charge and discharge processes with simoultaneously take place. Hence to charge to condenser fully the key `S_(1)` must be closed and `S_(2)` must remain open.
