Answer 2

Answer:

The number of turns in the secondary coil is 12.

Explanation:

Voltage in the primary coil of the transformer, V₁ = 220 V

Voltage in the secondary coil of the transformer, V₂ = 44 V

Number of turns in the primary coil of the transformer, N₁ = 60

Let the number of turns in the secondary coil of the transformer be N₂.

The transformer equation is given by,

V₁/V₂ = N₁/N₂

⇒ N₂ = (V₂/V₁) × N₁

   N₂ = (44/220) × 60

   N₂ = 12
