The transformer raises the voltage from 5V to 50V. There are 20 turns in the primary winding. How many turns are in the secondary winding?
To determine the required number of turns in the secondary winding of the specified transformer, we apply the equality: Uн / Uк = N1 / N2, whence we express: N2 = N1 * Uк / Un.
Variables: N1 – turns of the primary winding (20 pcs.); Uк – final voltage, secondary winding (50 V); Uн – initial voltage, primary winding (5 V).
Calculation: N2 = N1 * Uc / Un = 20 * 50/5 = 200 turns.
Answer: The secondary winding of the specified transformer must contain 200 turns.
