An inductor $L$ and a capacitor $C$ are connected in the circuit as shown in the figure. The frequency of the power supply is equal to the resonant frequency of the circuit. Which ammeter will read zero ampere

${A_1}$

${A_2}$

${A_3}$

None of these

Solution

(c) The frequency matches, resonance occurs. Given is parallel $LC$ circuit. Hence parallel resonance will occur. In parallel resonance circuit, current become zero. Hence ammeter $\mathrm{A}_{3}$ which is used to show total circuit current will read zero.
