|In the basic shunt regulator, the control element is a transistor (Q1) in parallel with the load.|

|Not only transistor, Zener diode can also be used as control element in shunt regulator.|
|Brajendra Kumar Mishra said: (Nov 3, 2013)|
|Correct Option is (A).
Zener diode always be used as a Voltage reference and Regulating device so answer will be (A).

Of Course Zener diode always be used as a Voltage reference in a basic shunt voltage regulator.
Zener diode used as control element ? Not.
So Answer([B].False) is correct.

|Zener diode's voltage remain same so it is sometime used a voltage regulator and some time a reference. So the statement can't be false totally.|

|In transistor shunt regulator, transistor is a control element.
While in zener shunt regulator, zener is a control element.

|Zener diode is only used as a reference, not a control element. Distinguish the difference.|
|Siddeshwar said: (Jun 18, 2017)|
|In question only mentioned control element.
Zener diode control the voltage.
|Sravan said: (Feb 6, 2020)|
|In shunt regulator, zener diode act as reference volage source means it is control element only.
So, A is correct answer.
