For the circuit below, solve for the following:
1.
RT
a. RT = R1 + R2 + R3
RT = 2K + 1K + 6K
RT = 9k ohms
2.
IT (pk), IT (p-p), IT (rms), IT (avg)
a. IT = VT / RT
IT = 120Vrms / 9kohms
IT = 13.33mA
IT pk = 1.412 X 0.
a. The calculations and the simulations seem to be very similar.
b. To design a circuit that reaches 24 mA in 2 seconds I would need to make sure that I have the
right amount of resistance and then allow for the proper amount of voltage drop to ensure tha

W4 Assignment - Inductance
1.
Calculate the inductance of a coil that induces 120V when the current through it changes at a rate of
5A/s.
L = Vl / di/dt
L = 120v / 5 a/s
L = 24 H
2.
Calculate the inductance of a coil that ind
For the circuit above, determine the following (express all answers in phasor form):
a. X C = 1/ 2pi x f x C
b. IR1 = VT/ R1
c. IC1 = VT/ X c
d. IT = IR1 + IC1
e. Zeq = VT/ IT tan = IC1/IR1
Given Parallel circuit Supply VT = 120Vrms f = 500Hz R1 = 300 ohm
The transient response (also known as the Natural Response) is the way the circuit
responds to energies stored in storage elements.
In any circuit, there is going to be a time delay between the input and the output of the
circuit, this is known as the tim

In the parallel circuit, I had trouble running the simulations, but this was due to the inductor in
this case being perfect. The inductor is created, within the confines of the simulation, it is
meant to be perfect, with having little resistance. So the v
