    thank you so much sir this was really helpful though i have a question, part 36 sometimes we use vpIp=vsIs and sometimes we use the formula that u used so when do we use each formula?

      It’s the same thing VI is power
      The idea is 100% or ideal means input power is equal to output power
      Here there was no current given so I just used power
