Question
A 0.1 henry inductor, a 4x10^(-3)
farad capacitor, a O ohm resistor,
and a voltage source having a value
of 180 cos 40ot volts (for t > 0 or t =
0) are connected in series. Let | = 0
and Q = 0 att = 0 for the circuit.
2. Which of the following is the
auxiliary equation for the
differential equation of the
circuit?
m^2 + 25 = 0
none of the other choices
m^2 + 2500 = 0
m^2 + 250 = 0
3. Which of the following is the
complementary solution of the
differential equation of the
circuit?
Qc = A cos 50t
Qc = A sin 40t
Qc = A cos 50t + B sin 50t
Qc = A cos 40t + B sin 40t
