as far as i know to calculate output of lm 317 we use this equation vout= 1.25*(1+R2/R1) and in my case vout is 8.194v. please tell me what about about the incoming voltage? why don't we consider that volatge in this equation? what if my inut voltage is around 8 volts? what would happen then?

LOL :D its not homework

Hello everyone ! can you please tell me how this whole circuit is working ? specially these ones, 1.whats happening at LM317's pins(in adjust and out) ? 2. what's the purpose of zener here? 3. purpose of transistor nd how is it working ? last question! how much time it will take to...

hello everyone i want to ask that what are the theories that proposes the wave nature of light and also those which proves the particle nature of light? list all the theories please ! P.S i don't want a complete description about those theories. thank you

thats exactly what i wanted to ask, as we know w=f.d here we can use d=4.5m but what about F?
