Consider the circuit shown in the figure below, where

R1 = 5.00 Ω,

R2 = 8.00 Ω,

and

= 6.00 V.

A rectangular circuit begins at the positive terminal of a battery labeled emf , which is on the bottom side of the rectangle. The circuit extends up and to the left to a 2.00 Ω resistor on the top side of the rectangle. To the right of the 2.00 Ω resistor, the circuit splits into two parallel horizontal branches.

  • The top branch splits into two parallel horizontal sub-branches. There is a 10.0 Ω resistor on the top sub-branch and a 5.00 Ω resistor on the bottom sub-branch. The sub-branches then recombine and the top branch extends to the right to a resistor of resistance R2.
  • The bottom branch contains a resistor of resistance R1.

The top and bottom branches then recombine and the circuit extends down and to the left until it reaches the negative terminal of the battery.
