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.

How do you find amperes when given volts and watts?
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
What is the Dimension of current?
Amperes (or amps)
What is 1000000 amperes in a number word?
1 microamplere
Was the matrix destroyed in transformers 2?
yes but it later fix at the end of transformers 2 revenge of the fallen
What does the letters MVA represent in electrical terms?
Mega volt amperes
What is mva?
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.
What is fullform of MVA?
milli volt amperes, unless it's MVA then it is Mega Volt Amperes. Such as in the use of large transformers
How do you calculate the of turn and the secondary voltage of the 15kw transformer?
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.
How do you calculate current capacity of transformer?
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.
How many amperes are in 400kVA at 220volts?
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.
How do you calculate volts with volt amperes?
Divide the circuits amperage into the volt amps and you will get the voltage.
How many watts is 8.6 amperes?
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.
How do you calculate the ratings of transformers?
just simple. f'ck up b'tch
What are transformers rated?
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.
How do you Calculate the voltage of a battery if the resistance is 20hms and the current is 0.35 amperes?
Use Ohm's law. V = I * R where V is voltage in volts, I is current in amperes, and R is resistance in ohms.
What is the method for calculating amperes and current?
To calculate amperes, you can use Ohm's Law: amperes = voltage ÷ 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.
How do you calculate 1 phase kwh from measuring amps?
You can't. Measure the amperes simply tells you what the current is.
