Consider the circuit in Fig. 3 with the following values for the voltage sources and the resistors. V = 12 Volts, V = 6 Volts, R = V a f R www "1 b 1 13 R3 100, R = R www i d 1 , R3 = 2 k, V Figure 3 a. Superposition theorem: Apply the superposition theorem to calculate the current 13 (10 points). b. Thevenin equivalent: Consider R3 to be the load resistor and everything else to be the source. Replace the source with its Thevenin equivalent and calculate the load current (10 points).
