Transformer (Magnetism & electromagnetic induction)
Vₛ/Vₚ = Nₛ/Nₚ = Iₚ/Iₛ
Where: Nₚ = Transformer, Nₛ = Nₛ, Vₚ = Vₚ, Vₛ = Vₛ
Solved example
Given: N_s = 7, V_p = 5, V_s = 10
Find: N_p (Transformer)
- Formula: Vₛ/Vₚ = Nₛ/Nₚ
- Rearranged for Nₚ: Nₚ = Nₛ·Vₚ/Vₛ
- Substitute the values: Nₚ = 5·7/10
- Result: Nₚ = 3.5
Answer: N_p = 3.5 ideal
