Question
A residential wiring circuit is shown in the figure. In this model, the resistor R3 is used to model a 250 V appliance (such as an electric range), and the resistors R1 and R2 are used to model 125 V appliances (such as a lamp, toaster, and iron). The branches carrying I1 and I2 are modeling what electricians refer to as the hot conductors in the circuit, and the branch carrying In is modeling the neutral conductor. Our purpose in analyzing the circuit is to show the importance of the neutral conductor in the satisfactory operation of the circuit. You are to choose the method for analyzing the circuit.(Figure 1)
Part A
Open the neutral branch and calculate Ip if R1=40?, R2=400?, and R3=8?.
Part B
Close the neutral branch and calculate Ip if R1=40?, R2=400?, and R3=8?.
