How to Calculate Transformer Load
A transformer changes alternating current (AC) voltage from one level to another for power companies, appliances and chargers. But the size of a transformer has little to do with the voltage, and everything to do with the amount of electric... Read More »

How to Calculate Transformer Power
A transformer is essentially two electrically-separate coils of wire wrapped around a magnet. The source voltage passes through the primary coil, producing a magnetic field which induces a voltage in the secondary coil. The ratio of the num... Read More »

How to Calculate Transformer Losses
The loss in a transformer compares the input, or primary power, to the output, or secondary power. Most transformer data show their input and output voltages and the current ratings of both sides. A step-up transformer increases voltage, bu... Read More »

Most transformers change one level of voltage to another, but the size of the transformer depends on the amount of overall power it must transfer. The formula P=IE, means power (P) equals current in amps (I) times volts (E). Since power equ...
