Resistance only
केवल प्रतिरोध

Reactance only
केवल प्रतिक्रिया

Resistance and reactance
प्रतिरोध और प्रतिक्रिया

None
कोई नहीं

Impedance $Z$ is the total opposition to AC current and combines resistance $R$ (real part) and reactance $X$ (imaginary part) as a complex quantity:

Z = \sqrt{R^2 + (X_L - X_C)^2}
