(b) 3 V in both the circuits.
(c) 0 V is circuit I and 3 V in circuit II.
(d) 3 V in circuit I and 0 V in circuit II.​

Answer 1

Answer:

Explanation:

In the Fig I , the key is open so no current flow in the ammeter. Thus the reading of voltmeter will be zero.

In the fig II, the key is closed and the current in the circuit I=
