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

Correct Answer: 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

Correct Answer: 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

Correct Answer: It has to dissipate more heat

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

Correct Answer: 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

Correct Answer: Minimum distortion
