Which transistor regulator is also known as 'Emitter-Follower Regulator'?Options:
a. Transistor Series Voltage Regulator
b. Controlled Transistor Series Regulator
c. Transistor Shunt Voltage Regulator
d.Transistor Current Regulator
Correct Answer: a. Transistor Series Voltage Regulator Explanation
The circuit configuration of transistor series voltage regulator is in such a manner that voltage at the emitter follows the base voltage.
Even the transistor in this type of set-up acts as a variable resistor whose value of resistance is determined by the base current.
This transistor is also known as pass transistor because it allows to pass the current that needs to be regulated through it.
