  2. Abhinaw kapoor says:

    sir,give me some tips how to study electrical machine.which topic should i pick first?

    • DC machine: emf equation, speed control of dc machine,power flow
      Transformer: equivalent circuit,voltage regulation,efficiency
      induction : power flow,torque speed characteristics,concept of slip, speed control
      synchronous: power equation,power flow,emf equation,salient pole machine power equation and emf equation.
      this much is important in machine..for detail u can join our facebook group for query
