    Hello everyone,
    does anyone know how to calculate the power dissipated by the load resistance assuming the SCR is ideal (lossless) ? if the average output voltage of the rectifier is 93% of its maximum output voltage

    we have Vrms=100v, 50Hz power supply and load resistance = 10 ohms

    ive figured i need to calculate a firing angle

    but unsure how to do so

    any help would be amazing

    Bruce

    That doesnt show how to work out the firing angle using the factors I have been given

    Is the firing angle a set figure when the SCR is ideal (lossless)??????
