Question 224: AC fundamentals

Question

A 110 V, 50 Hz, AC source is connected in the circuit (as shown in figure). The current through the resistance 55 $$\Omega$$, at resonance in the circuit, will be __________ A.

Accepted Answer

$$
\frac{1}{Z}=\sqrt{\left(\frac{1}{X_L}-\frac{1}{X_C}ight)^2}
$$
At resonance, $\mathrm{X}_{\mathrm{L}}=\mathrm{X}_{\mathrm{C}} \& \mathrm{Z} ightarrow \infty$
$	herefore \mathrm{Z}_{	ext {total circuit }} ightarrow \infty$
i.e, $\mathrm{I}=0$
