A colored band near one end of an actual diode is used to indicate the anode lead.

A popular semiconductor device called a diode is made by joining p- and n-type semiconductor materials.

The ______________ value of a full-wave signal is equal to 0.707 times the peak voltage.

Intrinsic semiconductors are semiconductors in their purest form.

In most cases, the LED voltage drop can be assumed to be

A reverse-biased diode conducts a small amount of current, called leakage current.

What diode is optimized for operation in the breakdown region and is often used as a voltage regulator?

The unfiltered output from a half-wave or full-wave rectifier is a ______________ dc voltage.

A graph of forward voltage versus forward current shows that a diode is a nonlinear device.
