Find the wire from the secondary of the transformer. If it's a step-down transformer the thicker wire is the secondary.
Measure its diameter in inches and calculate its cross-section area in square inches. The current rating for transformer wire is 1000 amps per square inch, or 1.55 amps per square mm.
I would assume you are speaking of AC circuits, and do not wish a long winded engineering primer. The basic formulas to calculate all: A=Amperes V=Volts W=Watts AxV=W , W/V=A, W/A=V So, to find Amps, divide voltage into the wattage A = W/V

Mega volt amperes
In electrical engineering it can be millivolt amperes, unless it's MVA then it is megavolt amperes. Such as in the use of large transformers.

First of all, transformers are rated in volt amperes, not watts. Secondly, in order to determine a transformer's turns-ration, you need to know its primary and secondary voltage ratings.
The secondary winding's current rating is the rated apparent power of the transformer (expressed in volt amperes) divided by its voltage rating (expressed in volts). This applies to both step down, and step up, transformers.
To calculate the amperes, you can use the formula: Amperes = Power (kVA) / Voltage. In this case, it would be 400 kVA / 220 V = 1818.18 Amperes approximately.
Divide the circuits amperage into the volt amps and you will get the voltage.
To calculate the total power consumption in watts, you can multiply the current in amperes by the voltage in volts. If the voltage is not known, you cannot directly convert amperes to watts.
just simple. f'ck up b'tch
Use Ohm's law. V = I * R where V is voltage in volts, I is current in amperes, and R is resistance in ohms.
A transformer's capacity is rated in volt amperes(V.A). This is the product of the secondary winding's current rating and voltage rating.
To calculate amperes, you can use Ohm's Law: amperes = voltage รท resistance. Current is the flow of electric charge, measured in amperes, that passes through a conductor in a unit of time. You can measure current using an ammeter in a circuit.
You can't. Measure the amperes simply tells you what the current is.
