Question
For the circuits shown in figures I and II, the voltmeter reading would be
Options
A.2V in circuit and 0V in circuit II
B.0V in both circuits
C.2V in both circuits
D.0 V in circuit I and 2 V in circuit II
Solution
In the circuit I, the key is open so current in the circuit is zero. Therefore voltmetergives 0 V reading . In the circuit II, the readied of the voltmeter is 2V.
