Block 4. LESSON 5 NORTON'S THEOREM Complex DC Circuits IN 2A RN 7.20 The final Norton equivalent circuit is shown in Figure 7C. I was calculated to be 2 amps as that was the branch current in the original circuit. R, was calculated to be 7.2 ohms as that was the equivalent resistance looking into the network from the terminals with the voltage source shorted. B Figure 7C. Network Analysis Now any value of load resistance may be placed across terminals AB and the circuit values of I, and E, may be easily calculated. Exercise 2: Network Analysis Using Norton's Theorem.
