Line regulation is determined by

In a semiconductor diode, electrons flow from:

A semiconductor having its leads labeled gate, drain, and source is best described as a:

The diode in which impurities are heavily doped is

When the rms output voltage of a bridge full wave rectifier is 20 V, the peak inverse voltage across the diodes is (neglecting the diode drop)

The varactor diode is usually

Pinch-off voltage VP for an FET is the drain voltage at which

Zener diodes are most commonly used in:

The basic semi-conductor amplifying device is the:

Bipolar transistors usually have:

When diode is forward-biased

Avalanche breakdown results basically due to

If you wish to reduce the current flowing in a field effect transistor, you could:

The average value of a half-wave rectified voltage with a peak value of 200 V is

When a voltmeter is placed across a forward-biased diode, it will read a voltage approximately equal to
