How does turns ratio affect voltage and current?

N₁/N₂ = V₁/V₂ = I₂/I₁. Step-up transformer (N₂>N₁) increases voltage, decreases current. Step-down does opposite. Power is conserved (minus losses): P₁ = P₂ for ideal transformer.

What is impedance transformation?

Z reflected to primary = (N₁/N₂)²·Z₂. This is used in audio amplifiers to match 8Ω speaker to 1000Ω amplifier output for maximum power transfer. Turns ratio = √(1000/8) = 11.18:1.

What is voltage regulation of a transformer?

VR% = (V_no_load - V_full_load)/V_full_load × 100%. Ideal transformer VR = 0%. Real transformers: 2-5% for distribution transformers, 5-10% for industrial. Low VR means voltage is stable under load.
