V PM =4 × 1=4 V <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/physics/c0d7f5c75c93a500e63873b33f1ab9a5-.png" /> V NM =((1/1+0.25)) 4=3.2 volt

Q. In the circuit shown, the current through the $4 Ω$ resistor is $1 A$ when the points $P$ and $M$ are connected to a d.c. voltage source. The potential difference between the points $M$ and $N$ is :-

0.5 volts

3.2 volts

1.5 volts

1.0 volt

$V_{PM} = 4 \times 1 = 4 V$

$V_{NM} = (\frac{1}{1 + 0.25}) 4 = 3.2$ volt
