A voltage wave has an amplitude of 800 V at the fundamental frequency of 50 Hz and its nth harmonic has an amplitude 1.5% of the fun- damental. The voltage is applied to a series circuit containing resistance 52, inductance 0.369 H and capacitance 0.122 µF. Resonance occurs at the nth har- monic. Determine (a) the value of n, (b) the maximum value of current at the nth harmonic, (c) the p.d. across the capacitor at the nth harmonic and (d) the maximum value of the fundamental current.
