Question

for a triac to conduct for one complete cycle of a sine wave, ______. the gate must be pulsed once at 0 degrees the gate must be pulsed at 0 degrees and at 180 degrees the gate must be pulsed at 0 degrees and at 270 degrees none of the above

Explanation:

A triac conducts in both half-cycles of a sine wave. A 0-degree pulse triggers conduction in the positive half-cycle, and a 180-degree pulse triggers conduction in the negative half-cycle, enabling full-cycle conduction.

Answer:

the gate must be pulsed at 0 degrees and at 180 degrees
