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

then we must agree that we disagree.

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