6. A single-phase full-wave ac voltage controller shown in below figure has a resistive load of \( R=10 \mathrm{Ohm} \) and the input voltage is \( \mathrm{V}_{\mathrm{s}}=120 \mathrm{~V}(\mathrm{rms}), 60 \mathrm{~Hz} \). The delay angles of thyristors \( T 1 \) and \( T 2 \) are equal: \( \mathrm{a}_{1}=\mathrm{a}_{2}=\mathrm{a}=\mathrm{p} / 2 \). Determine (a) the rms output voltage \( V_{o} \), (b) the input \( P F \), (c) the average current of thyristors \( I_{A} \), and (d) the rms current of thyristors \( I_{R} \).
