If an electric circuit contains a resistance R (ohms) and condenser of capacitance C (farads) in series;
and an emf E (volts), the charge q (coulombs) on the condenser is given by
dq
R-
Е.
dt
If R= 10 ohms, C=105 farad and E(t)= 100sin120rt volts,
a) Find q, assuming that q=0 when t=0
b) use i=dq/dt to find i, assuming that į=5 amperes when t=0
