Unit 5: Electricity & Magnetism

Note 4: Circuit Analysis


Reference: 16.7


Students prepare Summary of Kirchoff's Laws:


Current Voltage Resistance
Current Voltage Resistance


General Steps to Solving Circuits:

1) Reduce parallel elements to a series equivalent.

2) Determine the total resistance in the circuit.

3) Use Kirchoff's Laws to determine all possible voltages and currents.

4) Use V = IR (Ohm's Law) to determine 3rd quantity whenever two are known.

5) Summarize values in a chart.
