I see the open and closed circuit test on the transformer section I don't understand why we doing that(open and closed circuit test) can anyone explain and give some example?

? 600Ω || 300jΩ = 120 + j240 ?? I want to know how 600Ω || 300jΩ is equal with 120 + j240 ? what do i have to explain about? how 600 register parallel with 300johm is equal to 120+ j240??

stream king , yes that is my question

one of example of cauchy sequence show that = 1/n - 1/(n+k) and In the above we have used the inequality 1/(n+m)^2 <= ( 1/(n+m-1) - 1/(n+m) ) => i don't under stand where this come from and what is inequality? can you give other example?

resister // inductor -- calculate resulting impedance Hello, how 600Ω || 300jΩ = 120 + j240 ?? how do you get the value 120 + j240 from 600 register parallel wih 300jΩ inductor?

why inductance's current represent with di/dt? ps) and how do you make image big...

quantum expected value 1. why <x> is squeez between ψ* and ψ what we doing this? 2. for <p> [h/i d/dx ] is sqeeze between ψ* and ψ why is that? 3. if you put latter operator between ψ* and ψ what is going to happen? thank you
