I would like to know the origin of the following formula

I don't understand what's in the red circle. Why is the unit 's' and what does 's' stand for? Why must we divide the current at Open-circuit test by the voltage at Open-circuit test? I don't ...

Why connecting two secondary windings together in an aiding dot-orientation parallel configuration will result in no output?

I need clarification on what would happen if the transformer is in aiding dot-orientation parallel configuration as shown below. Would that be the same as connecting two batteries, in parallel, as ...

Why would an in series-opposition center-tapped transformer not be used to drive a circuit?

I understand that if a center-tapped transformer is connected in series-opposition as in the image below, there would be no voltage across both circuit terminals. But can the individual voltage ...

What is the sign convention for the primary counter balancing current of a 2-winding transformer?

In a two winding 1-phase transformer on load, Primary Current(I1) = No Load Current(Io) + Primary Counter Balancing Current(I2') So, We get I1 = Io + I2' We know I2' = K*I2, where K is the turns ratio ...

Do Grainger/Stevenson incorrectly describe an equivalent circuit for a transformer?

The equivalent circuit for a transformer, as shown above, is supposed to be consistent with the following equations: \begin{align} \small{\mathrm{Equation~2.22:}}~V_1&=(r_1+j\omega L_{11})I_{1} + (...
