Given that R=160ohms, L= 1H, C = 10^-4 F, E=20V
1a) kirchoff's law
b) the formulae for voltage drop across R, L, C
c) Relationship between charge and current
2) Apply the above to obtain a differential equation for charge
3) state the initial condition
4) use laplace transform to solve the differential equation to find charge
5) use your result to find current
