The thyristor shown in the circuit below is triggered at a phase angle of \( \pi / 5 \) in every positive half cycle of the applied voltage \( \mathrm{V}_{\mathrm{s}}=240 \mathrm{Sin} \omega \mathrm{t} \). Draw the voltage waveforms across the load and the Thyristor indicating timings of ON and OFF of the Thyristor. Calculate the average voltage, RMS voltage across the load (Lamp), and then determine: (a) the rectification efficiency (b) the form factor \( \mathrm{FF} \) (c) the ripple factor \( \mathrm{RF} \) (d) the peak inverse voltage PIV of thyristor
