    Finding Impendence if problem has a current transformer

    I know how to find the impendence/current on secondary side is using a voltage tx, but practice exam 101 solves for current with a current tx by not inverting turns ratio, so would the same logic apply if finding impendence?

    A simple single phase power line with a motor question

    For some reason I am not getting the answer. A single phase power line with a purely resistive impedance of 200 ohms per conductor delivers power to an induction motor that requires 800 watts input power. Determine the generator power delivered to the line and motor combination, assuming a line...

    Single phase Transformer Problem

    Thanks for the help, for some reason I was reading the 10 ohm resistance load as just being a resistance not the load, which as was pointed out allows the problem to be worked easily. Another lesson in reading the question/problems carefully.

    Single phase Transformer Problem

    Here is one that is simple, but I am stuck, any advice would be appreciated. A single phase. 1200:120 volt transformer has an equivalent impedance of 10j ohms referred to the low voltage side. Determine the applied voltage to the high voltage primary necessary to deliver rated voltage to a...
