A current of $3 \mathrm{amp}$. flows through the $2 \Omega$ resistor shown in the circuit. The power dissipated in the $5 \Omega$ resistor is
5 watt
4 watt
2 watt
1 watt
Solution
Potential difference across $2 \Omega=6 \mathrm{~V}$
Current through $5 \Omega=\frac{6}{6}=1 \mathrm{~A}$
Power dissipated in $5 \Omega=(1)^2 \times 5=5$ Watt
