A) reciprocal of the sum of the reciprocals of the branch resistances
B) product of the resistors divided by the sum of the resistors when the circuit has two resistors
C) value of one resistor divided by the number of resistors when the circuit contains two or more resistors of the same value
D) all of the above
E) b and c only

Quizplus · Accepted Answer

In a parallel circuit, the total resistance can be calculated using different methods depending on the specific conditions of the circuit. Option A describes the general formula for calculating total resistance in a parallel circuit, which applies universally. Option B provides a specific method for calculating total resistance when there are only two resistors in parallel, which is a simplification of the general formula. Option C describes how to calculate the total resistance when all resistors in the parallel circuit have the same value, which is another specific case of the general rule. Therefore, all these statements are correct ways to calculate total resistance in a parallel circuit under their respective conditions.
