Question

If 2A current passes through a 120 ohm resistance calculate the power of the device and write any two methods to increase the power of the device

Answer 1

Answer:

Answer :

Current flow = 2A

Resistance of device = 120Ω

We have to find

power dissipated by device

Formula of power dissipated by electric device in termas of resistance and current is given by

•

P = I² × R

P denotes power, I denotes current and R denotes resistance.

Let's calculate ☃

⇒ P = I² × R

⇒ P = (2)² × 120

⇒ P = 4 × 120

⇒ P = 480 watt
