Assignment
For this and all assignments, you should show enough work that the assignment is self supporting. Write out the problem, explain any researched information needed to solve the problem, and show your work in an organized manner. I encourage you as students to post questions onto Canvas concerning this assignment.
Nodal Analysis
Calculate the voltages of each node on the circuit, with reference to ground. Use the following procedure for each circuit.
1.Draw circuit
2.Label nodes
3. List KCL Equations
4. Perform Ohm's Law substitutions
5.Identify an equation per unknown voltage
6.Solve system of equations
7.Summarize final voltages for each node
8.Validate answers with LTSpice simulation

Mesh Analysis
Calculate the mesh currents of each mesh on the circuit. Use the following procedure for each circuit.
1.Draw circuit
2.Label meshes
3. List KVL Equations
4. Perform Ohm's Law substitutions
5. Identify an equation per unknown mesh current
6.Solve system of equations
7.Summarize final mesh currents for each mesh

DC Sweep Analysis
Calculate the voltages of each node on the circuit, with reference to ground. Use the following procedure for each circuit. Note that F1 is a current controlled current source (CCCS). It is 100 times the current going through V2, using passive sign convention. The details of F2 are shown to the right of the circuit.
1. Draw circuit, with V1 being 2 volts
2. Label nodes
3. Solve equations
4. Summarize final voltages for each node, with V1 being 2 volts
5. Validate answers with LTSpice simulation
6. Note the DC sweep option shown in the lower left hand corner of Figure 7[1] [2]. This sweeps V1 from 0 volts to 10 volts in .1 volt increments. Use this option to identify the range of inputs in V1 that meets the following criteria.
IV 2 > 0 (Current going through V2 is positive) and VC > .2 (Voltage of node C is higher than .2 volts above ground).
