Introduction OF Electric Current || Current Density || Current in a Conductor

The electric current in a discharging R-C circuit is given by i=i_0e^(-t/RC) where i_0 R and C are constant parameters and t is time. Let i_0=2.00A, R=6.00xx10^5 ohm and C=0.500 muF . a. Find the current at t=0.3 s. b. Find the rate of change of current at t=0.3 s. Find approximately the current at t=0.31 s.

In the equation AB = C, A is the current density, C is the electric field, Then B is

If C,R,L and I denot capacity resitance, inductance and electric current respecitively, the quantities having the same dimensions of time are (a) CR , (b) L//R , (c) sqrt(L//C) , (d) LI^(2)
