A silicon controlled rectifier (SCR) is a solid state device used for what functional purpose?

Correct Answer: Option B — functions like a switching device and controls relatively high load current

A silicon controlled rectifier (SCR) operates as a solid-state switching device capable of handling substantial load currents in marine power control circuits. Governed by IEEE 45 standards for power electronics, it remains latched in the conduction state until the forward current drops below its holding threshold.
