FAQs about Can a capacitor be considered as an open circuit
Is a capacitor an open circuit?
A capacitor is not well-described as an open circuit even in DC situations. I'd rather describe it as a charge-controlled ideal voltage source in that it can deliver and accept arbitrarily high currents at the cost of adapting its voltage depending on the delivered charge.
