Practice # 9 Semiconductors

The positive alternation.

A rectifier transforms AC into DC by limiting or regulating the direction of current flow.

Varactor.

The schematic symbol for a zener diode is a specific representation used in circuit diagrams.

Breakdown diodes.

When the circuit potential is equal to or in excess of the desired reverse bias voltage.

Alternating current (AC) to direct current (DC).

A half-wave rectifier only uses one half of the AC cycle, while a full-wave rectifier uses both halves.

To allow current to flow in one direction while blocking it in the opposite direction.

Its capacitance varies with the applied reverse voltage.
