Question

In an ac circuit, an inductor, a capacitor and a resistor are connected in series with XL=R=XC. Impedance of this circuit is: (A) 2 R 2 (B) Zero (C) R (D) R √2

Tardigrade Admin · Accepted Answer

Z =√( X L - X C )2+ R 2= R ∵ X L = X C

Q. In an ac circuit, an inductor, a capacitor and a resistor are connected in series with $X_{L} = R = X_{C}$ . Impedance of this circuit is:

$2 R^{2}$

Zero

$R$

$R 2$

$Z = (X_{L} - X_{C})^{2} + R^{2} = R$
$∵ X_{L} = X_{C}$

Q. In an ac circuit, an inductor, a capacitor and a resistor are connected in series with XL​=R=XC​. Impedance of this circuit is:

2R2

Zero

R

R2​

Z=(XL​−XC​)2+R2​=R ∵XL​=XC​

Q. In an ac circuit, an inductor, a capacitor and a resistor are connected in series with $X_{L} = R = X_{C}$ . Impedance of this circuit is:

$2 R^{2}$

$R$

$R 2$

$Z = (X_{L} - X_{C})^{2} + R^{2} = R$
$∵ X_{L} = X_{C}$
