No, the rating of the transformer, in watts, is the maximum amount of energy that can be safely drawn from the device. Any wattage load up to that limit is safe to connect as long as the voltage is correct to the load.

Can you use a 1000watts transformer with a 700 watts appliance?

Yes, you can use a 1000 watts transformer with a 700 watts appliance. The transformer's capacity should be equal to or greater than the appliance's wattage to prevent overloading or damage. In this case, the 1000 watts transformer has enough capacity to safely power the 700 watts appliance.


Do you have to use a transformer if your device have 900 Watts 220 V and 60 Hz with 7.5 amps?

If your device uses 900 Watts at 7.5 Amps, then it requires 120 volts. If you want to use it where the supplied current is 220 volts, then you'll need a transformer - but only if the device can operate on 50 Hz. Most places that use 220 Volts supply it at 50 Hz. If your device says it can operate on 50 Hz you can use a transformer.


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.


How many watts does a 22VA transformer have?

A 22VA transformer has a power rating of 22 watts. VA (volt-ampere) is a unit used to measure the apparent power in an electrical circuit.


How many watts does a 12 volt transformer consume to power a 50 watt down light?

If by "consume" you mean "waste as heat", that would depend upon the design of the transformer, but would typically be a few watts of heat loss.

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.

How do you found out which watts is using the most energy?

Watts is a unit of power, energy / time. Therefore, the energy consumption of a device is the amount of watts, multiplied by the time the device is turned on.


0.3A equals to how many watts?

You need to know the volts of the device to answer the question, if it's a household appliance (120v) then the answer is 36 watts, if it's an automobile device (12v) then the answer is 3.6 watts
