A residential wiring circuit is shown in the figure. In thismodel, the resistor *R*3 is used to model a 250 V appliance(such as an electric range), and the resistors *R*1 and*R*2 are used to model 125 V appliances (such as a lamp,toaster, and iron). The branches carrying **I**1 and**I**2 are modeling what electricians refer to as thehot conductors in the circuit, and the branch carrying**I***n* is modeling the neutral conductor. Ourpurpose in analyzing the circuit is to show the importance of theneutral conductor in the satisfactory operation of the circuit. Youare to choose the method for analyzing the circuit.(__Figure1__)

**Part A**

Open the neutral branch and calculate **I**p if*R*1=40?, *R*2=400?, and *R*3=8?.

**Part B**

Close the neutral branch and calculate **I**p if*R*1=40?, *R*2=400?, and *R*3=8?.
