How do you calculate the voltage of a transformer?
Divide the number of secondary windings by the number of primary windings, and multiply the source voltage by this ratio. This will give you the output voltage.
Why is high voltage used in transformers?
High-voltage transformers, also called potential transformers, are used to reduce or ‘step down’ high voltage values to lower safer values. Additionally, high-voltage transformers can be used to isolate equipment from high-power circuits. These types of transformers are essentially conventional wire-wound transformers.
How do you calculate current and voltage of a transformer?
If for some reason you need a larger transformer to operate appliances, you still divide the wattage by the voltage to find the current. For a 120-volt primary, 2000-watt transformer, divide 2000 by 120 for the current (2000 Watts /120 volts =16.67 amps). For a 240-volt, 3000-watt transformer, the current is 12.5 amps.
How do high voltage transformers work?
The core of the transformer works to direct the path of the magnetic field between the primary and secondary coils to prevent wasted energy. Once the magnetic field reaches the secondary coil, it forces the electrons within it to move, creating an electric current via electromotive force (EMF).

How does a transformer produce output voltage?
A basic transformer is made from two coils of wire; a primary coil from the ac input and a secondary coil leading to the ac output. the changing magnetic field induces a changing potential difference (voltage) in the secondary coil. the induced potential difference produces an alternating current in the external …
