Kirchhoff's Laws & Measuring Instruments

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

Show answer and solution

Answer: (c)

Walk from A to B along the current: potential drops by $IR$ across each resistor and by $E$ when going from + to − of the cell.
$V_A - 2(2) - 3 - 2(1) = V_B$
$V_A - V_B = 4 + 3 + 2 = 9\text{ V}$
So the answer is (c) 9 V.
