Answer

This problem is like the last problem: the only difference is the values of the current, voltage, and resistance of the resistor. Thus, we can approach this problem the exact same way. Thus, 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. After all, recall, a parallel circuit is like a fork in the road, meaning that an electron going through the circuit can "choose" which path to go through. Therefore, after you draw the circuit, be sure to make sure that when starting at one of the two nodes where the three wires intersect, there is a closed path along which you can go through any two of the circuit elements without going through the third one.
