Core Find the voltages and currents on both sides of an ideal transformer using the turns ration Reflect impedances through a transformer Identify and compute the no-load currents that flow in a non-ideal transformer Draw the no-load circuit model of a non-ideal transformer. For example, a farmer has a large, 480-V, 3-phase motor powering a well.
