EECT111 Notes
Using MultiSim, Excel and hand calculations create a set of notes that show how to:
1.) Multiple resistors combine in series and parallel.
2.) By example calculate RT, IT, PT, and all the nodal voltages, branch currents and power
dissipation of a resistor network.
3.) By example calculate the Thevenin Resistance and Voltage of a resistor network.
4.) Multiple capacitors combine in series and parallel.
5.) Multiple inductors combine in series and parallel.
6.) Using a simple RC circuit determine the
a.) Time Constant. Create a graph that shows the RC time constant as a function
of time
b.) Determine XC at a fixed frequency. Create a graph that shows how XC changes
as a function of frequency
7.) Using a simple RL circuit determine the
a.) Time Constant
b.) Create a graph that shows the RL time constant as a function of time
b.) Determine XL at a fixed frequency
d.) Create a graph that shows how XL changes as a function of frequency
