(b) A single-phase transformer has 2000 turns on the primary winding and 500 turns on the secondary winding. Winding resistances are R₁ = 20 and R2 = 0.125 2. Leakage reactances are X₁ = 80 and X₂ = 0.5 0. A purely resistive load with impedance Z₁ = 12 is connected to the secondary of the transformer. Neglect the magnetizing current. If the voltage applied at the terminals of the primary winding is 1200 V: (i) Find the voltage V₂ at the secondary terminals. V₂ = 292.94-4.67° A (ii) Determine the percentage voltage regulation of the transformer. %Reg = 2.42%

(b) A single-phase transformer has 2000 turns on the primary winding and 500 turns on the secondary winding. Winding resistances are R₁ = 20 and R2 = 0.125 2. Leakage reactances are X₁ = 8 2 and X2 = 0.5 0. A purely resistive load with impedance ZL = 12 is connected to the secondary of the transformer. Neglect the magnetizing current. If the voltage applied at the terminals of the primary winding is 1200 V: (i) Find the voltage V₂ at the secondary terminals. V₂ = 292.92-4.67° A (ii) Determine the percentage voltage regulation of the transformer. %Reg = 2.42%
