Like the previous problem, the problem in Figure 3 requires multiple principles to be
applied in order to find the solution. One principle is Ohm’s law (I 5 V/R) to determine
the total amount of resistance in the circuit. The total resistance is 12 V/2 A56 X.
There are two resistors in the circuit. The second principle that must be applied is that in
a series connection such as the given circuit, the resistances of different components (e.g.,
resistors) add up. One resistor (R1)is3 X, and, therefore, the resistance of the other (R2)
must be the total resistance minus the resistance of R1,6 X23 X53 X.
