this question is very easy but im out of idea how to find the answer.. pls help..

supply volt : 230V
load resistance : 20 ohm
load power : 2404.7W
rms load voltage : 219.3V
current 10.97A

wat is the average power loss in the triac, where it has threshold voltage Vo = 1.1V and slope resistance 5.1mili ohm..

 

Since this looks like homework you should post it in homework help - more members would tend to look there rather than here in the math area. Also if it is such an easy question you should attempt and post a solution - otherwise people are reluctant to help .....
