Electrical Engineering. Ideal Transformer at No-Load and Load. The transformer is a simple electrical machine, yet it exhibits a series of interesting and non-trivial electromagnetic phenomena. Therefore, to simplify its study, let's begin by simplifying the discussion. Therefore, let's introduce the following three simplifying assumptions. The two windings have no electrical resistance, so they do not disperse energy due to the Joule effect and do not produce voltage drops. Therefore, R1 = R2 = 0. The magnetic coupling is perfect; that is, all the flux produced by the primary winding is linked to the secondary winding. This means a coupling coefficient of k = 1. The magnetic core that channels the flux is ideal, so it exhibits no losses whatsoever. Furthermore, with a reluctance of R = zero, it can be magnetized with a zero, or rather infinitesimal, current.
