Description:
A bi-color LED is connected to an 60 Hz AC source and swung in a
circle. The resultant pattern is a series of arcs, alternating
red and green. When the LED is connected to a diode, or half wave rectifier, one color disapears to be replaced by a black gap.
The LED is connected to a full wave rectifier, the arcs are all
the same color, but separated by short dark areas as the voltage drops
to zero. With the addition of a filter capacitor, the dark areas disaprear.
Question? What would happen to the arcs of the swinging LED if the frequency were increased. |
