Question

2.
A SCR (Silicon Controlled Rectifier) is a
1. Device with 3 junctions
2. Device with 2 junctions
3. Device with 1 junction
4. Device with 4 junctions
Choice 1​

Answer 1

Answer:

silicon controlled rectifier or semiconductor controlled rectifier is a four-layer solid-state current-controlling device. ... SCRs are unidirectional devices (i.e. can conduct current only in one direction) as opposed to TRIACs, which are bidirectional (i.e. charge carriers can flow through them in either direction).

Answer 2

A SCR is a device with 3 junctions.

1. Device with 3 junctions
