ELECTRONIC PRACTICE - Quiz

1) How the gate terminal of N channel JFET biased?

Gates are reverse biased Gates are forward biased Gates are forward biased with drain Gates are reverse biased with source

2) Which device is made up of using the methods of point contact, grown, diffusion and alloy junctions?

Inductor Resistor Capacitor Transistor

3) Why the collector region is physically made larger than emitter region in a transistor?

It has to dissipate more heat Output taken from collector terminal Base collector region is reverse biased Collector region always operate with high voltage

4) What is the function of a transistor if emitter to base and collector to base are forward biased?

Acts as an amplifier Acts as an oscillator Acts as an open circuit Acts as a closed switch

5) What is the main advantage of a class A amplifier?

Minimum distortion Maximum current gain Maximum voltage gain Minimum signal to noise ratio losses
