Question

1. reducing the supply voltage, interruption, and forced commutation are all methods of accomplishing what? __________

a. turning on an scr
b. turning off an scr
c. turning on a schockley diode
d. turning on a triac

Explanation:

Reducing supply voltage, interruption, and forced commutation are techniques used to stop the conduction of an SCR (Silicon - Controlled Rectifier). These methods remove the necessary conditions for the SCR to remain in the conducting state, thus turning it off.

Answer:

B. turning off an SCR
