The Thevenin Method of Circuit Analysis NAME _______________________ STUDENT ID # _______ Procedure: 1.
Measure and record the voltage across the load and the current flowing through the load. V(load) = _________ V I(load) = _________ mA.
2.
Thevenin Analysis Steps: a) Remove the load resistor and measure the voltage across the load terminals. This is the open circuit load voltage, also referred to as the Thevenin voltage. Vth = ___________ V b) Remove all voltage sources (only one in this circuit) and replace with a SHORT circuit. Measure the resistance appearing across the LOAD terminals (A to B). This is the Thevenin resistance. Rth = __________ c) Construct a new series circuit, consisting of a voltage source equal to the Thevenin voltage from step a), a resistance equal to the Thevenin resistance from step b) and the original load resistance. d) Measure and record the voltage across the load and the current flowing through the load. V(load) = _________ V I(load) = _________ mA.
3.
Conclusions: What conclusions can be drawn regarding the Thevenin method of analysis from these observations? ___________________________________________ ___________________________________________
4.
Calculations. Use the Thevenin method to calculate load voltage and current in this circuit. Show all calculations.
