How many 120 volt 7 amp draw lights can be run on a 15 kva single phase transformer?
To determine how many 120-volt, 7-amp lights can be run on a 15 kVA transformer, first convert the transformer capacity to watts: 15 kVA equals 15,000 watts. Each light draws 120 volts * 7 amps = 840 watts. Dividing the transformer capacity by the wattage of each light gives 15,000 watts / 840 watts per light ≈ 17.86. Therefore, you can run a maximum of 17 lights on a 15 kVA transformer.
How many 12 volt 50 watt bulbs can be used on the 100 va transformer?
To determine how many 12-volt, 50-watt bulbs can be used on a 100 VA transformer, first convert the transformer's capacity from VA to watts, which is effectively the same for resistive loads (100 watts in this case). Each 50-watt bulb requires 50 watts, so you can divide the total available watts by the wattage of one bulb: 100 watts ÷ 50 watts/bulb = 2 bulbs. Therefore, you can use 2 of the 12-volt, 50-watt bulbs on a 100 VA 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 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.
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.
How many watts does a charger draw in the US that is listed as 100V to 240V and 22VA parenthesis100Vparenthesis since I want to use it with 12V car inverter?

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 design buck- boost transformer primary and secondary voltage?

What is the recommended power rating for a 16v 30va transformer?
The recommended power rating for a 16V 30VA transformer is 30 watts.
If the output of the secondary of a transformer is 1300 watts and the input of the primary is 1800 watts the percentage efficiency would be?
72 percent
How many watts does a 24V - 40VA transformer put out?
A 24V - 40VA transformer can output up to 40 watts. The "VA" (volt-amperes) rating indicates the apparent power, which in this case is equivalent to the real power in watts for resistive loads. Therefore, at 24 volts, it can deliver a maximum current of approximately 1.67 amps (40 VA / 24 V).
7200 volt 25kw transformer how many amps at 240 single phase?
The formula you are looking for is I = W/E. Amps = Watts/Volts.
