Question:

The potential difference $(V_A-V_B)$ between points A and B in the given figure is:

Options:

+17 V

+10 V

3 V

-3 V

Correct Answer:

+17 V

Explanation:

The correct answer is Option (1) → +17 V

According to Kirchoff's voltage law,

$ΔV=0$

$⇒V_A-5-10-2=V_B$ [V = 1R (Ohm's law)]

$⇒V_A-17=V_B$

$⇒V_A-V_B=17V$
