Power is applied from the 360 VRMS, 60 Hz, to a 80 ohm light bulb by an SCR, controlled with a phase angle firing circuit. Calculate the power that the light bulb dissipates if the SCR is fired at every zero crossing. Answer in W. Calculate the power that the SCR dissipates if it is fired at every zero crossing (VSCR on = 1.5 V). Answer in W. If the firing angle is 130o, when must the trigger's LED be grounded? Answer in ms. Determine the VRMS delivered to the load given a firing angle of 130°. Use the equation. Answer in V.
