1. Set up the circuit in Fig. 3.1. 2. Measure the current (IL), through Road and the voltage (VL), across RLoad. 3. Find the Thevenin equivalent circuit seen by RLoad (i.e. the equivalent circuit between nodes A & B, with RLoad removed from the circuit). To get the equivalent circuit, follow these steps: a. Remove Road from the circuit. b. Measure VAB (open circuit voltage = Thevenin Voltage =VT). c. Set all the voltage sources to zero volts, and use the ohmmeter to measure the equivalent resistance between nodes A & B (This is the Thevenin Resistance=RT).
