134. Usually the forward voltage triggering method is not used to turn-on the SCR because a) it increases losses b) it causes noise production c) it may damage the junction & destroy the device d) relatively it’s an inefficient method

Explanation: In forward voltage triggering the middle junction breaks down without any
gate signal and pushes the device into the conducting state. This method can
permanently damage the J2 junction and make the device useless.
