Sol. C = 12.0 μF = 12 * 10^-6
emf = 6.00 /v, R = 1 Ω
T = 12 μc, i = I base 0 e^-t/RC
= CV/T = e^-t/RC = 12 * 10^-6 * 6/12 * 10^-6 * e^-1
= 2.207 = 2.1 A
b) Power delivered by battery
We known, V = V base 0 e^-t/RC (where V and V base 0 are potential VI)
VI = V base 0l e^-t/RC
⇒ VI = V base 0l * e^-1 = 6 * 6 e^-1 = 13.24 W
c) U = CV^2/T (e^-t/RC)^2 [CV^2/T = energy drawing per unit time]
= 12 * 10^-6 * 36/12 * 10^-6 *(e^-1)^2 = 4.872.
