In order to do this problem, it is necessary to draw a parallel circuit containing all three elements. In order to draw a circuit in parallel, draw a rectangle, and then draw a vertical line connecting the midpoints of the two horizontal sides. After this, there will be three vertical lines. Place a circuit element on each line so that any electrons that go through that particular line go through that circuit element.

Work Step by Step

Once we have made the circuit, we need to address the four different ways in which the elements can be connected in the given configuration. Thus, in your first diagram, arbitrarily define the direction of the current and the positive and negative of the voltage source. In the second figure, switch the positive and negative of the voltage source and leave the current in the same direction. In the third figure, switch the direction of the original current and leave the originally defined positive and negative of the battery the same. Finally, in the fourth figure, switch both the defined direction of the current generator and the positive and negative of the battery.
