Question

Consider the network of four resistors shown in the diagram, where R1 = 2.00ft , R2 = 5.00 ft , R3 = 1.00ft , and R4 = 7.00 Ohm. The resistors are connected to a constant voltage of Find the equivalent resistance RA of the resistor network. magnitude V (Figure 1) Two resistors of resistance R5 = 3.00Ohm and R6 = 3.00Ohm are added to the network, and an additional resistor of resistance R7 = 3.00Ohm is connected by a switch, as shown in the diagram..(Figure 2) Find the equivalent resistance RB of the new resistor network when the switch is open. Find the equivalent resistance RC of the resistor network described in Part B when the switch is closed.

Explanation / Answer

Part A

Req=10/7+1+7=66/7=9.42 ohm

for part B u hav to give figure no 2

part B
