Physics 202 SI Session Worksheet #5 Problem 1 In the circuit shown below, voltmeter V1 indicates 10.0 V when the switch is open. (a) What does voltmeter V2 indicate? What do the ammeters A1 and A2 indicate? What is the emf V(0) of the independent voltage source? (b) The switch is closed and voltmeter V1 indicates 8.0 V, V2 indicates 6.0 V, A1 indicates 0.50 A, and A2 indicates 0.75 A. Use this information to find the numerical values of R3, R2, R1 and r. DC V(0) V1 A1 V2 A2 R1 R2 R3 r Problem 2 Determine the current in each branch of the circuit shown below. 8.00 Ohm 4.00 V 5.00 Ohm 1.00 Ohm 12.0 V 1.00 Ohm 3.00 Ohm

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
