A component in a test chamber is at a constant temperature. Energy is transferred to and from the component only by radiation. The average power emitted by the component is 480 W.
State the average power absorbed by the component.
The component emits 1.44 × 106 J of energy. Calculate the time taken.
Use the equation
time=energy transferredpower\text{time} = \dfrac{\text{energy transferred}}{\text{power}}time=powerenergy transferred
