An op-amp comparator in a firing circuit can produce waveforms at the output of up to 20 V peak-to-peak without any distortion. An inverse cosine-based firing circuit with a voltage range from +10 to -10 (reference voltage) is used to produce a gating signal for the SCR at the desired delay angle. if the reference voltage is 5.92 volts, the delay angle (in degrees) would be: O A. None of the other choices are correct. OB. 41 O C. 139 O D. 131 O E. 49
