Question

What is Imax​ shortly after the capacitor has been fully charged, but before you start the discharge process? Explain!

5. While the capacitor is charging, the current flowing through the circuit can be modeled by the equation:
I
= Imare-t/r
(Eq. 5)
Where:
I = the instantaneous current flowing through the circuit
Imax = the most current flowing through the circuit (at t = 0)
t = time after the circuit closes
T = the time constant of the resistor capacitor network
Eg. 5 describes how the current goes from Imax to zero during the charging process.
Same is true while the capacitor is discharging. Current starts with it's maximum value, at time t = 0, but then slowly decreases to
zero as a function of time. We can use Eq. 5 for the discharging process as well.
Rearranging Eq. 5, and taking the natural log of both sides of the equation allows us to linearize the equation.
In(Imax/I) = (1/T)t (Eq. 6)
6. What is Imax shortly after the capacitor been fully charged, but before you start the discharge process? Explain!
Hint: zero
