Question

Please Answer all the following questions!.

Thanks.

A 27 F capacitor is charged to 132 V and is then connected across a 330 resistor. What is the initial charge on the capacitor? Answer in units of C. 008 (part 2 of 4) 10.0 points What is the initial current just after the ca- pacitor is connected to the resistor? Answer in units of A 009 (part 3 of 4) 10.0 points What is the time constant of this circuit? Answer in units of ms. 010 (part 4 of 4) 10.0 points How much charge is on the capacitor after 6.06 ms? Answer in units of uC.

Explanation / Answer

Initial Charge = Q = CV = 27 x 10-6 x 132 = 3564uC

Initial Current = V/R = 132/330 = 0.4 A

Time Constant = RC = 330 x 27 x 10-6 = 8.91ms

Q = Q0(1 – e-t/RC) = 3.564 x 10-3x(1-e-6.06/8.91) = 1758.6uC
