question 11
the triac operates similar to two scrs ______.

• connected in inverse parallel
• placed back-to-back

Explanation:

A triac is a bidirectional semiconductor device that conducts current in both directions, which is functionally equivalent to two silicon-controlled rectifiers (SCRs) connected in inverse parallel (also described as placed back-to-back). Both configurations allow current flow in opposite directions, matching the triac's operating principle.

Answer:

A. connected in inverse parallel
B. placed back-to-back
