Impedance: A series circuit has a resistance of 4.0 Ω, a reactance (due to the capacitance) of 21.0 Ω, and a reactance (due to the inductance) of 17.0 Ω. Find the impedance of the circuit.

Question

Quizplus · Accepted Answer

The impedance of a series circuit is given by the square root of the sum of the squares of the resistance and the reactances. In this case, the impedance is:Z = sqrt(R^2 + (XL - XC)^2) = sqrt(4.0^2 + (17.0 - 21.0)^2) = 5.7 Ω
