When using the product over sum method of determining the total resistance of a parallel circuit, you would ____.
A) multiply the total of R(1) times R(2) by the total of R(1) plus R(2)
B) multiply the total of R(1) plus (R2) by the total of R(1) times R(2)
C) divide the total of R(1) times R(2) by the total of R(1) plus R(2)
D) divide the total of R(1) plus R(2) by the total of R(1) times R(2)

Question

Quizplus · Accepted Answer

To use the product over sum method of determining the total resistance of a parallel circuit, you need to divide the total of the product of each resistor by the sum of the resistance values. Therefore, the correct equation is (R(1) x R(2)) / (R(1) + R(2)).
