Current Question (ID: 20266)

Question:

$\text{Find the magnitude of potential difference in volt between A and B in given circuit.}$

Options:

1. $2 \text{ V}$
2. $0$
3. $3 \text{ V}$
4. $6 \text{ V}$

Solution:

$\text{Hint: } V = IR$ $i = \frac{9}{3} = 3 \text{ A}$ $\Rightarrow V_1 - 4 \times 1.5 = V_A = V_1 - 6$ $\Rightarrow V_1 - 1.5 \times 2 = V_B = V_1 - 3$ $V_A - V_B = (V_1 - 6) - (V_1 - 3)$ $= -3$ $|V_A - V_B| = 3 \text{ V}$
