DC Network Theorems Unit 7 – Thevenin Circuits
Exercise 2 – Thevenizing a Dual Source Network
EXERCISE OBJECTIVE
When you have completed this exercise, you will be able to simplify a dual source network by
applying Thevenin's theroem. You will verify your results by comparing calculated and
measured values
DISCUSSION
- With RL removed, use the superposition method to determine the Thevenin equivalent
voltage across points A and B. - With RL removed and both voltage sources shorted, determine the equivalent resistance
(RTH) looking into the circuit from points A and B. - VTH, RTH and RL form a simple series circuit known as Thevenin’s equivalent circuit.
