The transformer changes the voltage from 200 V to 1000 V. There are 20 turns in the primary winding. Determine the number of turns in the secondary winding.
To calculate the value of the number of turns in the secondary winding of the used transformer, we use the equality: N1 / N2 = Uн / Uк, from where we express: N2 = N1 * Uк / Un.
Variables: N1 – the number of turns in the primary winding (20 pcs.); Uк – final voltage, secondary winding (1000 V); Un – initial voltage, primary winding (200 V).
Calculation: N2 = N1 * Uк / Un = 20 * 1000/200 = 100 turns.
Answer: The secondary winding of the used transformer contains 100 turns.
