Light dimmers cause incandescent lights to dim or
brighten depending on the adjustment. Normal household current is 120 volts at
60 hertz alternating current. This means that the current changes direction
within the circuit 60 times per second. The dimmer uses the alternating aspect
of the current to reduce the current to the bulb without reducing the voltage.
The dimmer only works with incandescent lights and will not work with
fluorescent or other forms of light bulbs.
