The frequency response of an ac amplifier shows decreased voltage gain at low frequencies because of the effects of capacitive reactances.

Question

Quizplus · Accepted Answer

Capacitive reactances have an inverse relationship with frequency, meaning that as the frequency decreases, the capacitive reactance increases. This causes the signal to have a harder time passing through the capacitor, resulting in decreased voltage gain at low frequencies.
