Consider the diagram shown below. A voltmeter of resistance \[150\Omega \]. is connected across A and 5. The potential drop across and C measured by voltmeter is
A)29V
B)27V
C)31 V
D)30V
Correct Answer:
C
Solution :
When voltmeter is connected across A and B, the equivalent resistance of the circuit is \[benzyl>allyl>{{3}^{\circ }}>{{2}^{\circ }}>{{1}^{\circ }}>Me>\] \[\text{I}\] \[\text{II}\] Current, \[\text{III}\]. Therefore, potential drop across B and C is \[\text{IIIIII}\] \[\text{IIIIII}\] \[\text{IIIIII}\]
