5. (a) Draw the equivalent circuit of transformer and derive its condition for maximum efficiency. (3) (b) A single-phase 3500/500 transformer has the following winding resistances and reactances: R1 = 0.7 Q2, R2 0.011 Ω, Χ1 = 3.6 Ω, X2 = 0.045 2. Calculate the equivalent impedance of (a) the primary in terms of secondary winding, (b) the secondary in terms of primary winding and (c) the total impedance of the transformer in terms of the primary (2) =
