- You charge an initially uncharged 65.9 mF capacitor through a 41.5 2 resistor by means of a 9.00 V battery having negligible internal resistance. Find the time constant t of the circuit. What is the charge Q on the capacitor 1.59 time constants after the circuit is closed? Q = What is the charge Qo after a long amount of time has passed? Qo =A simple RC circuit consisting of a 10.0-µF capacitor in series with a resistor. Initially, the switch is open. The capacitor has been charged so that the potential difference between its plates is 100.0 V. At t = 0 s, the switch is closed. The capacitor discharges exponentially so that 2.0 s after the switch is closed, the potential difference between the capacitor plates is 37 V. In other words, in 2.0 s, the potential difference between the capacitor plates is reduced to 37 % of its original value. Determine the numerical value of the resistance R (in Ω).A circuit consists of a series combination of 6.50 kΩ and 5.00 kΩ resistors connected across a 50.0 V battery having negligible internal resistance.
