When finding the total resistance of a series-parallel combination, the most important step is:
A) to know how to use Ohm's law
B) to know the value of the total current.
C) to know the value of the source voltage
D) to define the series and parallel relationships.

Question

Quizplus · Accepted Answer

Defining the series and parallel relationships is crucial because it determines how you calculate the total resistance. In a series circuit, resistances add up directly, while in a parallel circuit, the reciprocal of the total resistance is the sum of the reciprocals of each resistance. Understanding these relationships is essential before applying Ohm's law or considering current or voltage values.
