5) The voltage across the capacitor is 0 V when t=0 sec.
The current in the circuit will be = (V/R) = 12/(1.4×10^3) = 8.57×10^(-3) Amp (approx)
6) Initially the capacitor doesn't have any charge. As time goes on the charge is accumulated in the capacitor.
So, initial charge on the capacitor is 0 C
8)We know,
Q = C.V.[1-e^(-t)]
here, Q = charge on the capacitor.
C =capacitance of the capacitor= 1.8 F
V = supplied voltage= 12 V
t = number of time constant= 1.
Now, Q= 1.8×12 [1- e^(-1)]
=> Q = 13.654 C
The charge on the capacitor after one time constant is 13.654 C.
Please comment if you have any doubt and like if it helps.
Happy learning.
