Detailed Solution

A variable resistor offers resistance in the dimmer switch. If the resistance offered for the switch is more, the intensity of the bulb glow is lesser. Conversely, if the resistance offered for the switch is less, the intensity of the bulb glow is higher. Thus, if the switch is turned to the right, there is a brighter light, and if the switch is turned to the left, there is dimmer light.
