WINDING RESISTANCE

Any practical or non-ideal transformer possesses resistance in primary and secondary windings. Due to the presence of resistance, the practical transformer is equivalent to an ideal transformer in which the resistances are connected in series with each winding shown in Figure (a). R₁ and R₂ in Figure (a) indicate the resistance of primary and secondary windings of an actual transformer.
