DC Network Theorems Unit 5 – Kirchhoff's Solution with 2 Sources
Exercise 2 – Kirchhoff's Current Law/2 Sources
EXERCISE OBJECTIVE
When you have completed this exercise, you will be able to apply Kirchhoff's current law to a
circuit having two voltage sources. You will verify your results by using measured data.
DISCUSSION
- Circuits containing two voltage sources can be analyzed using Kirchhoff’s current law.
- Assume a current direction for circuit elements that have no explicit indication of current
direction. - Node equations are written by applying Kirchhoff’s current law to each circuit node.
- Each current can be rewritten as a voltage / resistance relationship.
- Any negative current solution indicates that the assumed current direction was incorrect.
