PURPOSE: To demonstrate rectification of 60 Hz AC by a diode and by a bridge rectifier.
DESCRIPTION: A single diode can be used as a half-wave rectifier or a bridge rectifier as a full-wave rectifier, as per the circuits below. An inductor and a capacitor are used to filter out the ripple from the resulting output. A load must be present for the circuit to work
REFERENCES: (PIRA 5L30.10) See Demonstration Reference File.
EQUIPMENT: Variac, isolation transformer with adapter, half-wave rectifier (diode), full-wave rectifier (bridge rectifier), 1 Henry 90 ohm choke, 30 microfarad capacitor, 470 ohm load resistor, with oscilloscope on scope/TV cart.
SETUP TIME: 10 min.
