Answer:
Power, P = 30 W
Step-by-step explanation:
We have,
Voltage drop of a circuit is 60 V
Resistance of the resistor is 120 ohms
Current across the circuit is 0.5 A
It is required to find the power conducted by the resistor. Power conducted by a resistor is given by :

V and I are voltage and current

So, the power conducted by the resistor is 30 watts.
