22. The electric current in a charging R-C circuit is given
by i = i,
e r where i., R and C are constant
parameters of the circuit and t is time. Find the rate of
change of current at (a) t = 0, (b) t = RC, (c) t = 10 RC.
The electric current in a discharging R-C circuit is given
by i = i, et ke where i,, R and C are constant parameters
and t is time. Let i, = 2:00 A, R=6:00 x 10'12

Hope the current equation is i = i* e^(-t/RC) [since R,C,time parameters are mentioned]
di/dt = i* e^(-t/RC)* -1/RC ....(i)
When , t = 0
di/dt = i * e^0 * -1/RC = -i/RC
When, t= RC
di/dt = i* e^(-RC/RC) * -1/RC = i*e^-1 * -1/RC = - i/eRC
When, t= 10 RC
di/dt = i * e^(-10 RC/RC) * -(1/RC) = i*e^-10 * -1/RC = - i/e^10 * RC
Couldn't figure out the second part.
