Find current, resistance and potential difference in an electrical circuit.

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 similar resistance of 5 ohms each. The emf is the same in both diagrams and is 10 volts.

a. In which diagram is the current through R1 greater? (Circle the correct choice)
a. LEFT
b. RIGHT
c. BOTH THE SAME
b. In which diagram is the the magnitude of the potential difference across R2 greater?
a. LEFT
b. RIGHT
c. BOTH THE SAME
c. Concerning the diagram on the right, find out the current through R3 (Show all of your work and reasoning to receive full credit)
