Examples for Semiconductors
Example #1
Problem:
Identify and describe the pictures below:
A half-wave rectifier. This can be used as an AC-DC converter.
A forward-biased diode. The current shown is allowed to flow.
A pnp transistor.
A full-wave rectifier. During both halves of the cycle, current flows from left to right thus producing a purely positive signal.
A reverse-biased diode. Current is not allowed to flow in the direction shown.
The circuit-diagram symbol for a transistor.
