An RLC circuit has a 12- $\Omega$ resistor connected to an inductor with 44 $\Omega$ reactance and a capacitor with 21 $\Omega$ reactance. The effective resistance as seen by the source (impedance) is
A) 26 $\Omega$
B) 12 $\Omega$
C) 23 $\Omega$
D) 21 $\Omega$

Question

Quizplus · Accepted Answer

The effective resistance is the square root of the sum of the squares of the resistance and the reactance. In this case, the effective resistance is:```sqrt((12^2) + (44^2) + (21^2)) = 26 $\Omega$```
