Today we learnt how to manipulate AC circuits, There are 8 different that we learnt from our DC circuit :
Our first problem is to solve find Potential difference across capacitor of DC circuit
First we converted all time dependent part into phasor dependent part, then we applied nodal analysis to solve for the potential difference across the node:
Our second Problem we used Mesh analysis to find current. since the component are already in the phasor mode, we can directly apply mesh analysis on each loop, and uses the matrix to solve for each current.
On Our third Problem we used Superposition method to solve our previous problem. TO solve using superposition method we analyze the current for only one source at a time by only opening one source at a time and then added each of the current together. Current source become an open circuit when we turn it off, while voltage source turns into short circuit when we turned them off
Our last Lecture was to convert a circuit into it's Thevenin/Norton equivalent:
First we calculated voltage across point B to found our equivalent Thevenin Voltage
In order to find our equivalent thevenin resistor, we turned off our current source and connected the circuit with an independent source across B and ground, we then calculated the voltage across point B to find the voltage, equivalent Thevenin resistor is equal to the voltage across B divided by the current
