Question

The potential difference between $A$ and $B$ in the following figure is

• A. 32 V
• B. 48 V
• C. 24 V
• D. 14 V

Answer 1

Answer: (B)

48 V

Answer 2

From the given circuit
$V_A - (6 \times 2) - 12 - (9 \times 2) + 4 - (5 \times 2) = V_B$
or $\, \, \, \, \, \, \, V_A - 12 - 12 - 18 + 4 - 10 = V_B$
or $\, \, \, \, \, \, \, \, \, \, \, \, \, \, \, V_A - V_B = 48 \,volt$
