Conclusion Laboratory

The document summarizes designing and analyzing an AC circuit with various components. It describes how the author used circuit theorems to calculate the current and voltage in each component and compare these values to simulations. They then modified the circuit to find its total impedance and calculated the capacitor value needed for unity power factor. The author also determined the circuit's resonance frequency by simplifying it until an inductor and capacitor were in series parallel with resistors. Overall, the exercise demonstrated that network theorems can accurately determine electrical characteristics in AC circuits and how resonance frequency differs from power factor correction.

We had design a circuit diagram that consists of 16 components such as inductor, capacitor and resistor

with an AC source and specified frequency. Then we are required to determines the electrical
parameters in each component such as current and voltage using the theorem that was tackled
previously in the network theorems of Electrical Circuits 1. As we solve those current and voltage, we
compare it to the measured values in the simulated circuit. In addition we compute for the total
impedance of the network and determine the value of capacitor for unity power factor. In the same
manner, we simulate a new setup and compare the total current and total power (S,P,Q). Lastly we
compare the resonance frequency of the circuit.

To solve for the electrical parameters, We then further simplified the circuit until we arrived at its
simplest form, an impedance ZT = 10.34597418+j5.794601038 Ω connected in series to a source of
220V, 60Hz. Upon finding the total impedance of the circuit, we then started computing for the current
and voltage of each component through current division by retracing the transformations we did to our
circuit. we observed that both the values measured by the simulator and manually computed using the
method were very close, if not the same, to one another. We were able to compute the electrical
parameters of each component and get the whole decimal which shows how accurate we were able to
compute for them.

As the presentation above, we got the values of the current and voltages same as in the measured
values. The values of the Apparent Power from the initial setup and the unity power factor set up has
slight differences. In order to solve for resonance frequency for the activity’s resonance frequency
component, we first looked for the step in our circuit’s simplification when this was possible. We were
able to create a circuit in which a resistor and capacitor are linked in series, and the two of them are
then linked in parallel with an inductor, which is linked in series with yet another resistor. After
computing the resonance frequency of the streamlined circuit, we solved for the capacitance and
inductance of the capacitor and inductor

All things considered, this exercise demonstrated that the theories covered in the network of electrical
circuits could precisely answer for electrical characteristics in AC circuits. Finding a circuit’s resonance
frequency and performing power factor correction both aim to eliminate the circuit’s reactive power,
which would ultimately cut down on power losses. The two’s differences, though, are in how they go
about achieving that objective. While resonance frequency relies on determining the frequency at which
the reactance of the capacitor and inductor in the circuit would cancel each other out, power factor
correction relies on identifying the capacitor or inductor that would balance the reactive power of a
circuit. Our expertise has been greatly expanded by this practice in the field of electrical engineering .
