output vrms from firing angle of triac......

[sachinkp21587]

Hello all,

i am trying to change the power to a ac load i.e. relay ( in proteus) by help of TRIAC.
i am able to change the power as i checked it in the oscilloscope that the waveform is changing as per my firing pulses.

Now my question is how to calculate the firing angle for generating known AC voltage if i am using 230VAC 50Hz supply as input to TRIAC.
