8.2: Capacitance and Capacitors
For an ideal capacitor, leakage resistance would be infinite and ESR would be zero. Unlike resistors, capacitors do not have maximum power dissipation ratings. Instead, …
Does a capacitor have a resistance?
Impedance is the total opposition to current flow in an AC circuit, and for a capacitor, it varies with frequency. While an ideal capacitor in theory does not have any …
