The junction rule describes the conservation of which quantity? Note that this rule applies only to circuits that are in a steady state.

Apply the junction rule to the junction labeled with the number 1 (at the bottom of the resistor of resistance R_{2}).

Apply the loop rule to loop 2 (the smaller loop on the right). Sum the voltage changes across each circuit element around this loop going in the direction of the arrow. Remember that the current meter is ideal.

Now apply the loop rule to loop 1 (the larger loop spanning the entire circuit). Sum the voltage changes across each circuit element around this loop going in the direction of the arrow.
