B. Two resistors of resistance R5= 3.00 and R6= 3.00 are added to the network, and an additional resistor of resistance R7= 3.00 is connected by a switch, as shown in the diagram.(Figure 2)Find the equivalent resistance of the new resistor network when the switch is open. Express your answer in ohms.

C. Find the equivalent resistance of the resistor network described in Part B when the switch is closed. Express your answer in ohms.
