Question

At time t=0, an initially uncharged capacitor of 20

Answer #1

Time constant for the circuit ? = R * C

=
100 * 20 * 10^{-6}

= 0.002 s

C * V_{0} = 20 *
10^{-6} * 6

=
1.2 * 10^{-4} C

a. Charge at the capacitor is given by

q = C
* V_{0} *
(1 - e^{-t/?})

t = 0.0010 s

q = 1.2 *
10^{-4} *
(1 - e^{-0.0010/0.002})

= 4.722*10^ -5 C
