A series AC circuit has a resistance 8 Ω and a reactance of 6 Ω. The impedance of the circuit is :
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 10 Ω
The impedance (Z) of an AC circuit with resistance (R) and reactance (X) is -
$Z=\sqrt{R^2+X^2}$
Given,
$X=6Ω$ and $R=8Ω$
$Z=\sqrt{8^2+6^2}=10Ω$
