A light bulb is basically a resistor that gets so hot that it glows, emitting light. For this tutorial we will assume the resistor in the light bulb is ohmic (that means Ohm's law applies to the resistor). The rate of energy emitted by the light bulb is its output power, commonly referred to as luminosity (brighter means more luminous). Hook up a light bulb to a 5-V battery. Right-click (or control-click) on the light bulb, and change its resistance. How does the brightness of the light bulb depend on its resistance?
A. The brightness of the light bulb is independent of its resistance. It only depends on the voltage of the battery.
B. The light bulb gets brighter as the resistance is increased.
C. The light bulb gets dimmer as the resistance is increased.
