In the figure there's a circuit with an emf E=21V, two resistors R1=35kΩ and R2=5.5kΩ, two capacitors C1=25μF and C2=22μF and two switches S1 and S2.
b) Find the time constant for this configuration of the circuit.
c) Find how much charge will be stored in C2 after time t=1.3τ seconds.
After t=10τ seconds, we open switch S1 and close switch S2. Mark current time as t′=0. In this configuration, capacitor C2 discharges through the resistor R2.
d) Find the charge stored on the capacitor C2 as the switch S1 was turned off.
e) Find the current throught the resistor R2 at time t′=1.5τ.
f) Find the time from t′=0, that will be taken by the capactor to loose half of its charge.
