PhysicsInteger+4 / -1Question 59 of 90

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.

An inductor L and capacitor C connected in parallel, that combination in series with a 55 Ω resistor across an AC source.

Your answer

Answer and worked solution

Official answer: 0

Parallel LC at resonance. The tank's impedance is (ideally) infinite, so no current flows through the series 55 Ω resistor.

Answer: 0

Topics:LCR circuits and resonance
