Question:

The potential difference between the points A and C in the given circuit is:

Options:

2 V

3 V

5 V

7.5 V

Correct Answer:

7.5 V

Explanation:

The correct answer is Option (4) → 7.5 V

Now, Voltage across AD = 10 V

$R_{eq}=4+2+2=8Ω$ [Connected in series]

$∴I=\frac{V}{R}=\frac{10}{8}$ [By ohm's law]

$V_{AC}=V_{AB}+V_{BC}$

$=4×\frac{10}{8}+2×\frac{10}{8}$

$=7.5V$
