Figure P.2.1 - Circuit #2
In Figure P.2.1, the voltage sources V1 = 3V, V2 = 6V, and V3 = -6V.
Resistors: R1 = R2 = R4 = R5 = R7 = 7500, R3 = R8 = 1.5kQ, and R6 = 3kQ.
1. Calculate the following from the perspective of terminals A and B. Show all work.
a. Thevenin voltage (VTH)
b. Thevenin resistance (RTH)
C. Norton current, also called the short-circuit current (Isc)
2.
Use your results to fill in the appropriate values and draw the Thevenin and Norton equivalents
as you did in Part I.
3. Attach a 1k( load resistor RL across terminals A and B in Figure P.2.1 and calculate the
voltage across and current through RL for the new circuit.
4.
Attach a 1kQ load resistor RL across terminals A and B in the equivalent circuits that you drew
and calculate the voltage across and current through RL for the new circuits.
