Question

Quizplus · Accepted Answer

The bulk resistance of the emitter diode becomes important in high-power applications where large current flows through the diode. The bulk resistance, which is the resistance of the semiconductor material surrounding the emitter, can result in significant power dissipation and affect the overall performance of the circuit. In low-power applications, the bulk resistance is typically negligible, and in low/high-frequency applications, other factors such as parasitic capacitance and inductance become more significant.
