21.6 DC Circuits Containing Resistors and Capacitors
Capacitors, like batteries, have internal resistance, so their output voltage is not an emf unless current is zero. This is difficult to measure in practice so we refer to a capacitor''s voltage rather than its emf. But the source of potential difference in a capacitor is fundamental and it is an emf.
