In other words, if the voltage in the secondary winding is 1\/10th of the voltage in the primary winding, then the current in the secondary winding will be 10 times the current in the primary winding.<\/p>\n<p>In this case, the voltage in the secondary winding is 10 V, which is 1\/10th of the voltage in the primary winding, which is 100 V.
