Question
PartI
S,
Give the symbolic expression for the emf E using KVL for the circuit with S1 closed and Sz open. Give your answer in terms of the current I, resistor R,
capacitors C1 and Cz and charges stored in the respective capacitors Q, and Q2.
Use * to denote product and / to denote division. So to group the product of, say, a and b_1 write a b_1. And to write a ratio of say, c_1 and d write
C_1/d. To add the product and ratio write a*b_1 + c_1/d.
a)Write the mathematical expression for emf E.
E=
29 kN, two capacitors C1 = 3.3 µF and C2 = 4.4 µF and
In the figure there's a circuit with an emf E = 19 V, two resistors R1 = 22 kl and R2
two switches S and Sz.
b) Find the time constant for this configuration of the circuit.
Time constant T
Give your answer up to at least three significance digits.
ms
c) Find how much charge will be stored in C2 after time t = 0.9T seconds.
Charge stored in C2
Give your answer up to at least three significance digits.
PartII
After t = 10r seconds, we open switch S, and close switch S2. Mark current time as t' = 0. In this configuration, capacitor Cz discharges through the
resistor R2.
d) Find the charge stored on the capacitor C2 as the switch Si was tumed off.
Charge stored
Give your answer up to at least three significance digits.
e) Find the current throught the resistor R2 at time t' = 0.67T.
Current
Give your answer up to at least three significance digits.
f) Find the time from t' = 0, that will be taken by the capactor to loose half of its charge.
Time taken to discharge
Give your answer up to at least three significance digits.
