The primary winding of the transformer is connected to a network with a voltage of 20 V. The voltage at the terminals of the secondary winding is 200 V. specify all correct statements. 1) the transformer is a step-up 2) the transformation ratio is 10 3) the transformation ratio is 0.1
•Answer:
1) the transformer is a step-up
3) the transformation ratio is 0.1
•Explanation:
1) Since the voltage applied to the primary winding is less than to the secondary winding, the transformer is a step-up
3) K = U1 / U2
K = 20/200 = 0.1
