Turn-on and turn-off times of transistor depend on _________(a) Static Characteristic(b) Junction Capacitance(c) Current Gain(d) Voltage GainThe question was asked by my college professor while I was bunking the class.My query is from Modified Speed Torque Characteristics of DC Series Motors in chapter Characteristics of DC & AC Motors of Electric Drives

Answer» CORRECT option is (b) Junction Capacitance

The explanation: The depletion LAYER capacitance and diffusion capacitance affects the TURN-on and turn-off BEHAVIOR of transistors. DUE to these internal capacitances, transistors do not turn on instantly.
