Question

In the circuit shown, reading of the potentiometer is

Difficult

A

0.67 V
B

4.66 V
C

2.64 V
D

3 V

Solution

(1)
Current in the circuit $i = \frac{10 + 6}{1 + 0.5} A = 10.67 A (c l o c k w i s e)$
$\begin{array}{l} N o w, V_{B} + 6 - 10.67 \times 0.5 = V_{A} \\ \Rightarrow V_{A} - V_{B} = 0.67 v o l t . \end{array}$
