A transformer has a 2000-coil secondary and a 500-coil primary. The current flow in the primary coil is 5 amperes. Find the current flow in the secondary coil by using the following equation:
primary turns Primary current
------------------- = ----------------------
Secondary turns Secondary Current

The voltage output of the secondary is directly proportional to the ratio of the secondary to the primary; 4:1 in this case.
The amperage induced in the secondary is indirectly proportional to the ratio of the secondary to the primary.
So the voltage in the secondary windings will be 4-times the primary voltage and the amperage will be 1/4th of the primary amperage; 1.25 in this case. (Sorry. A case of brain fade!)

Current in the secondary is 4 times the primary, which is 20 amps.
