Question

what are rectifier? Give the define of Transistor Configuration​

Answer 1

Answer:

This is the answer.

Explanation:

THE TRANSISTOR RECTIFIER

This simple circuit consisting of a transistor, a biasing diode and a few resistors can rectify a.c as low as 0.3V or even less. The recitfication can be for positive half cycle or negative half cycle depending on the type of transistor(pnp/npn respectively) chosen.

Bipolar Transistor Configurations

Common Base Configuration – has Voltage Gain but no Current Gain. Common Emitter Configuration – has both Current and Voltage Gain. Common Collector Configuration – has Current Gain but no Voltage Gain.

Answer 2

Explanation:

what are rectifier?

• A rectifier is an electrical device that converts alternating current, which periodically reverses direction, to direct current, which flows in only one direction. The reverse operation is performed by the inverter. The process is known as rectification, since it "straightens" the direction of current

Give the define of Transistor Configuration?

• The common collector transistor configuration is also known as the emitter follower because the emitter voltage of this transistor follows the base terminal of the transistor. The voltage gain of this transistor is unity, the current gain is high and the o/p signals are in phase
