FAQs about Can capacitors be short-circuited
Are capacitors a short circuit?
In fact, that's exactly what you do. Capacitors are only short circuits when you consider the "small signal" component after you found the DC linearized point. So capacitors are open when considering the DC component, then shorts (or at least small negative imaginary impedance) when solving for the non-DC small signal response.
What happens if a capacitor is short?
Assuming a perfect short, the current would be limited only by the ESR which tends to be very low. The high current through a low resistance causes significant heating due to the power dissipated by the ESR, determined by P = I^2*R. This heating degrades the capacitor and can cause long-term damage.
