Question: The diagram on the left below shows two resistors in series with an ideal battery, in the diagram on the right; a third resistor has been added in parallel with R2. The three resistors show all have the same resistance of 5 ohms each. The emf is the same in both diagrams & is 10 volts.

[1.] In which diagram is the magnitude of the potential difference across R2 greater?
(A.)RIGHT
(B.)LEFT
(C.)BOTH THE SAME

[2.] In which diagram is the current through R1 greater? (Circle the correct choice)
(A.)RIGHT
(B.)LEFT
(C.)BOTH THE SAME
[3.] Concerning the diagram on the right, calculate the current through R3 (Show all of your work & reasoning to receive full credit)
