Question

The potential difference between points $A$ and $B$ in a section of a circuit is shown:

• A. $5volts$
• B. $1volts$
• C. zero
• D. $13volts$

Answer 1

The correct option is D $13volts$

According to Kirchhoff loop law,

$V_A-2\times 3-3-1\times 4+2-2=V_B$

$V_A-V_B=13V$

Option $\text{D}$ is the correct answer.
