A 110 V, 50 Hz, AC source is connected in the circuit (as shown in figure). The current through the resistance 55 Ω, at resonance in the circuit, will be __________ A. Numerical answer type. Work it out, then open the answer.

Answer: 0. At resonance, the parallel L-C combination has infinite impedance. No current flows from the source through the series 55 Ω resistor. Current through 55 Ω = 0 A
