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.

When a vertical beam of light passes through a transparent medium, the rate at which its intensity i decreases is proportional to i(t), where t represents the thickness of the medium (in feet). in clear seawater, the intensity 3 feet below the surface is 25% of the initial intensity i0 of the incident beam. what is the intensity of the beam "10" feet below the surface? (give your answer in terms of i0. round any constants or coefficients to five decimal places.)
