Title: An RC circuit is connected across a DC voltage source through an open switch. Th Post by: ppk on Mar 6, 2012 An RC circuit is connected across a DC voltage source through an open switch. The switch is closed at t = 0 s. Which of the following is a correct statement regarding this circuit?
A) The charge on the capacitor after four time constants is about 98% of the maximum value. B) The charge on the capacitor after one time constant is about 25% of its maximum value. C) The charge on the capacitor after one time constant is about 50% of its maximum value. D) The voltage on the capacitor after two time constants is about 14% of the maximum value. E) The voltage on this capacitor after two time constants is about 100% of its maximum value. Title: Re: An RC circuit is connected across a DC voltage source through an open switch.
