How many turns are in the secondary winding of the transformer, if there are 20 turns in the primary, and the transformer changes the voltage from 200V to 1000V?
Initial data: N1 (number of turns in the primary winding of the transformer) = 20 turns; U1 (voltage value at the ends of the primary winding) = 200 V; U2 (voltage value at the ends of the secondary winding) = 1000 V.
The number of turns in the secondary winding can be found from the ratio: U1 / U2 = N1 / N2, whence N2 = U2 * N1 / U1.
Let’s do the calculation:
N2 = 1000 * 20/200 = 100 turns.
Answer: There are 100 turns in the secondary winding of the transformer.
