The maximum value of VCE in a transformer-coupled class A amplifier will be greater than VCC. This is caused by
A) the input biasing network.
B) the efficiency characteristics of the amplifier.
C) the counter emf produced by the transformer primary.
D) the natural relationship between VCE and VCC.

Question

Quizplus · Accepted Answer

The maximum value of VCE in a transformer-coupled class A amplifier can exceed VCC due to the counter emf (electromotive force) produced by the transformer primary. This occurs because the transformer can store energy in its magnetic field and release it as additional voltage, which can momentarily increase the voltage across the transistor beyond the supply voltage (VCC).
