MCQ
In the circuit shown, potential difference between $X$ and $Y$ will be
- AZero
- B$20 \mathrm{~V}$
- C$60 \mathrm{~V}$
- ✓$120 \mathrm{~V}$
✓
Answer
Correct option: D.
$120 \mathrm{~V}$
As resistance $\propto$ Length Resistance of each arm $=\frac{12}{3}=4 \Omega$
$\Rightarrow R_{\text {effective }}=\frac{4 \times 8}{4+8}=\frac{8}{3} \Omega$
$\Rightarrow R_{\text {effective }}=\frac{4 \times 8}{4+8}=\frac{8}{3} \Omega$
