Resistance and potential difference in an electrical circuit

Reference no: EM1312993

Question: 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.

[A] Concerning the diagram on the right, calculate the current through R3

[B] In which diagram is the current through R1 greater?

RIGHT
LEFT
BOTH THE SAME

[C] In which diagram is the magnitude of the potential difference across R2 greater?

RIGHT
LEFT
BOTH THE SAME
