A 2.00-nF capacitor with an initial charge of 5.83 �C is

discharged through a 2.26-k? resistor.

(a) Calculate the current in the resistor 9.00 �s after the

resistor is connected across the terminals of the capacitor. (Let

the positive direction of the current be define such that dQ dt

> 0.)

=___mA

(b) What charge remains on the capacitor after 8.00 �s?

=___�C

(c) What is the (magnitude of the) maximum current in the

resistor?

=___A  Edit Comment  Solutions

a)

i = (V/R) exp(-t/RC)

i = (q/RC) exp(-t/RC)

i = (5.83e-6/(2.26e3*2e-9)) exp(-9e-6/(2.26e3*2e-9))

i = 175.65

mA

b)

Q = q0 exp(-t/RC)

Q = (5.83e-6) exp(-8e-6/(2.26e3*2e-9))

Q = 0.993 ?C

c)

i = (V/R)

i = (q/RC)

i = (5.83e-6/(2.26e3*2e-9))

i = 1.293 A  Edit Comment  Close Choose An Image
