What is 12v 60va equals in amps?
Enough to make your mother’s panties drop on the floor.
How many watts is 8 amps?
It's 120 x 8 for things with a power factor of 1, like electric heaters, irons or incandescent bulbs. If the item connected has a power factor less than 1, like electric motors, televisions, computers or CFL bulbs, you have to multiply by the power factor. <<>> The formula you are looking for is Watts = Amps x Volts.
How do you determine watts per square foot and total volt amp?
For lighting using CFL bulbs you can use 10 square feet per watt. The volt-amps is the volts times the amps, or the watts divided by the power factor. Most CFL bulbs are marked with the voltage and the current.
How much does it cost to run a 5 watts transformer?
If the transformer uses 5 watts per hour you need to know what you are paying per 1000 watts from your power company. If you pay lets say $3.00 for 1000 watts then when your transformer burns 1000 watts it cost you $3.00 your cost will be $3.00 for 200 hours run time.
Does voltage divided by watts equal the current?
Electric power is not defined as current divided by voltage. Electric power (Watts) is equal to amps times voltage
How many kilo watts in 10kv?
at first point you should determine the also the secondary voltage of the transformer, secondly you should explain what is the application of this transformer. if you want a special transformer, it is you to decide how much power is needed to be transferred via transformer, and designer tells you it is economical or not. by the way, if i want to refer you to a standard close to your application, following sizes are available for a 20kv/400v transformer: 50kVA,100kVA, 150, 200,315,500,630,800,1200,1600,2000,2500 and 3500kVA i hope this helps you
Will ampere go up in step down transformer?
Transformers transformer voltage and current, but power stays constant (minus transformer losses, which are typically minor). Power is typically measured in watts or killowatts. A watt is 1 ampere times 1 volt (P = V*I). Thus if a 117 VAC transformer (primary winding) is rated at 10 amps, it is capable of producing 1170 watts. If it's secondary steps down the voltage to 12 volts then it is capable of handling 97.5 amps (97.5X 12 =1170 watts).
How do you design buck- boost transformer primary and secondary voltage?

What are the power of light bulbs meauserd in?
The unit of measurement used to find the power of the bulb is watts. Voltage is the flow of electricity, so make sure not to confuse the two.

Why rating of transformer is given in kva and that of motor in kw?
A motor's output is measured in watts because it has to supply energy to a mechanical load. The rate at which energy is supplied to a mechancial load is expressed in watts (it wouldn't make sense to express it in electrical units!). A transformer's output is expressed in volt amperes, because this is the product of the transformer's rated output voltage and its rated secondary current -the product of voltage and current in a.c. systems is the volt ampere. In order to express its output in watts, you would need to know the power factor of the load which it supplies (power equals voltage times current times power factor), and the manufacturer has no means of knowing this.
How many amps in a low voltage light bulb?
Look on the light bulb for the voltage and the power in watts. Then divide the watts by the voltage and that gives the amps. Some CFL bulbs also state the current as well as the voltage and power, which is because they can have a poor power factor.
How many watts is 8 amps?
It's 120 x 8 for things with a power factor of 1, like electric heaters, irons or incandescent bulbs. If the item connected has a power factor less than 1, like electric motors, televisions, computers or CFL bulbs, you have to multiply by the power factor. <<>> The formula you are looking for is Watts = Amps x Volts.
What size ground wire for a 30 kva transformer?
The size of grounding wire is based on the amperage output of the transformer. The voltage of the transformer needs to be stated. Without this voltage a calculation can not be made. Amps = Watts/Volts = 30000/?.
What is in watts of a bulbs that operates at 40 voltage with a current of 0.5?
Watts equal volts times amps, which is 40 x 0.5 or 20 watts.
Electrical power of light bulbs is measured in what?
Watts.
Why transformer rated kva?
The correct symbol for kilovolt amperes is 'kV.A, not kva. A volt ampere is the product of the transformer's secondary rated voltage and its rated current. It is not rated in watts, because the transformer designer has no idea what sort of load is to be applied to the transformer, and it is the load that determines the amount of watts, not the transformer.
