Question
Two batteries and three resistors are connected as shown in the figure
Part A
Determine the magnitude of the current that flows through 6.0 -V battery when the switch is open?
part B
Determine the magnitude of the current that flows through 9.0 -V battery when the switch is open?
Express your answer using two significant figures.
Part C
When the switch is closed no current flows throught the 6.0 V battery. Find the current flowing through the 9.0 V battery.
Part D
What is the value of the resistor connected to the switch?

Switch is open so R to the right of switch is meaning less , Apply Kirchoff voltage law in loop in the left
+6-9-4I-2I=0
-3-6I=0
I=-0.5
I=0.5 A Anticlockwise , Same answer for part A and B
c) As switch is closed 6 V is meaning less as no current
in smaal loop
-IR-4I+9=0
in the small loop to the right
6-9+4I=0
I=3/4 A = 0.75 A
D) -0.75 R-4*0.75+9=0
-0.75R+6 =0
R= 6/0.75 = 8 Ohm
