Explanation:

Zener diode as a constant voltage source:
- This statement is true. A Zener diode is commonly used as a voltage regulator to maintain a constant voltage across its terminals, regardless of variations in the input voltage or load resistance.

SCR as a silicon rectifier with a gate electrode:
- This statement is true. The Silicon Controlled Rectifier (SCR) is a type of semiconductor device used for power control. It acts as a rectifier with an additional gate electrode to control the flow of current from the cathode to the anode.

Gate electrode on the FET corresponds to the collector in bipolar transistor:
- This statement is false. In a Field-Effect Transistor (FET), the gate electrode corresponds to the base in a bipolar junction transistor, not the collector. The gate electrode in an FET controls the flow of current between the source and drain terminals, similar to how the base in a bipolar transistor controls the current flow between the emitter and collector.

Therefore, the false statement in the given options is option C.
