In the circuit shown in the given figure, power dissipated

Home » Network Theory » Network theory miscellaneous » Question

In the circuit shown in the given figure, power dissipated in the 5Ω resistor is—

1. Zero
2. 80W
3. 125W
4. 405W

Correct Option: A

The given circuit:

The circuit can be modified as shown

– 5I + 20 – 10 I – 20 – 4 I = 0
or
19 I = 0
or I = 0
Therefore, the power dissipated in 5Ω resistor is zero.
