The potential difference $(V_{A} - V_{B})$ between the points A and B in the given part of the circuit

Options:

Answer:

Solution:

Applying Kirchhoff's voltage law from point A to point B:

$V_{A} - I R_{1} - V - I R_{2} = V_{B}$

Substituting the given values ( $I = 3 A$ , $R_{1} = 4 Ω$ , $V = 5 V$ , $R_{2} = 2 Ω$ ):

$V_{A} - (3 \times 4) - 5 - (3 \times 2) = V_{B}$

$V_{A} - 12 - 5 - 6 = V_{B}$

$V_{A} - 23 = V_{B}$

$V_{A} - V_{B} = 23 V$

Answer: 23 V
