The tungsten filament in an incandescent light is really a resistor and the power dissipated by the tungsten resistor as heat is released as light via a process known as blackbody radiation.
a. The ac voltage that is supplied from a wall plug to the incandescent light is 170V sin[(377 rad/s)t]. If the current flowing through the light is 350 mA sin[(377 rad/s)t], determine the power that the light is consuming.
b. What is the resistance R of the tungsten filament?
c. How much energy is being used during the one period of the sine wave.
