1. Superposition theorem: Consider the circuit in Fig. 1. It is required to calculate the voltage across the 500 resistor by applying the superposition theorem. 10 100 250 C. 500 5A Figure 1 a. Consider that the voltage source is zero. What effect does it have on the 25.02 resistor? (1 points). b. Use the current division rule to calculate the current through the 500 resistor. Use KCL to calculate the current through the 100 resistor (2 points). Use Ohm's law to calculate the voltage across the 5002, when the current source is only operating (1 points). d. Consider that the current source is zero and draw the simplified circuit (1 points). e. Calculate the current flowing through the 500 resistor (2 points). f. Calculate the voltage across the 500 resistor when the voltage source is only operating and use the superposition theorem to calculate the same voltage when both sources are operating together (2 points).
