For series AC circuits containing both resistance and inductive reactance, total opposition to current flow cannot be found by simply adding ohmic values or oppositions to current.

Question

Quizplus · Accepted Answer

In series AC circuits with both resistance (R) and inductive reactance (XL), the total opposition to current flow, known as impedance (Z), is found by calculating the square root of the sum of the squares of R and XL (Z = √(R^2 + XL^2)), due to the phase difference between resistance and reactance.
