What happens when class B amplifier is in a quiescent state?(a) No current flows through the transistor(b) Maximum current flows through the transistor(c) Half of the maximum current flows through the transistor(d) Quarter of the maximum current flowsI had been asked this question during an online exam.My doubt stems from Class B Amplifiers in section Power Amplifiers of Electronic Devices & Circuits

Answer»

The correct CHOICE is (a) No current flows through the transistor

The best EXPLANATION: When the transistor is in a QUIESCENT state, no input is applied ACROSS the base TERMINAL of the transistor and hence no current flows through the transistor.
