I'm trying to calculate the primary current for the last example in the first section of transformers(worksheet). The equation I normally use works for both primary and secondary currents if the primary voltage and current are in phase.
Ip = Np^2 * Vp
------------
Ns^2 * Rload
This equation works to give the secondary current in a situation where the primary current shift is from -90 to 0, but the primary is not accurate.
How do i go about calculating the primary current?
