Answer:

The power dissipated by a resistor will be: 0.4 watt

Explanation:

Given

  • Current I = 0.02 A
  • Resistance R = 1000 Ohm

To determine

  • The power dissipated by a resistor

Using the formula to determine the power dissipated by a resistor

Power = I²R

           = (0.02)² × (1000)

           = 0.0004  × 1000

           = 0.4 watt

Therefore, the power dissipated by a resistor will be: 0.4 watt
