The figure shows a circuit that illustrates the concept of loops, which are colored red and labeled loop 1 and loop 2.
Loop 1 is the loop around the entire circuit, whereas loop 2 is the
smaller loop on the right. To apply the loop rule you would add the
voltage changes of all circuit elements around the chosen loop. The
figure contains two junctions (where three or more wires meet)--they
are at the ends of the resistor labeled R3....
