When analyzing electronic circuits, capacitors are often treated as
A) an open for ac and a short for dc
B) an open for dc and a short for ac
C) a large resistor for high frequencies
D) an ac amplifier

Question

Quizplus · Accepted Answer

Capacitors block direct current (DC) but allow alternating current (AC) to pass through. This is because the capacitor's impedance decreases with increasing frequency. At DC (0 Hz), a capacitor acts as an open circuit, while at high frequencies, it can be considered a short circuit.
