Question

The transformation ratio in a transformer is (1-primary, 2-secondary, N-turns, E-voltage):

• A. \(\dfrac{N_1}{N_2}\)
• B. \(\dfrac{N_2}{N_1}\)
• C. \(\dfrac{N_1}{E_2}\)
• D. \(\dfrac{E_1}{N_2}\)

Hint:

Turns ratio affects voltage transformation: \( \dfrac{V_1}{V_2} = \dfrac{N_1}{N_2} \)

Answer 1

The Correct Option is A

The transformation ratio of a transformer is the ratio of the number of turns in the primary coil to the number of turns in the secondary coil: \[ \text{Turns ratio} = \dfrac{N_1}{N_2} \]
