Is the time it takes to charge a capacitor in an RC circuit to of its maximum value longer or shorter than one time constant? Is the time it takes to discharge a capacitor to of its initial charge longer or shorter than one time constant? Explain your answers.
Answer to relevant QuestionsUse Kirchhoff’s loop theorem to explain why the current in an RC circuit that is discharging a capacitor decreases as time goes on.
