Will a 30 watt transformer damage a device needing only 15 watts?

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.

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 do you decrease watts?
If the device you are trying to reduce watts in is not fluorescent and not mechanical (a fan or motor, for example) use a light dimmer. If the device is motorized, try a variac transformer (just type "variac" on eBay and you'll find them). You decrease watts by reducing one of the two components that make up the formula W = I x E. e.g. 1000 = 10 x 100, 500 = 10 x 50, 500 = 5 x 100.
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.
How much energy is consumed if device is rated at 1000 watts?
A device rated at 1000 watts consumes 1000 joules per second.

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?
how to designing 2000 watts buck boost transformer
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 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.
What device increases the voltage?
watts
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

Does a 600 watt garden lights transformer pull 600 watts all the time or just the load from the lights you have on it?
Watts are power. If the lights were mostly or totally switched off, you'd have a circuit generating 600W of heat somewhere if the transformer still took 600W, not only that, but when you switched on, the 600W that the transformer was consuming, would not disappear, so the total drain would be 1.2kW. ---- Don't understand the above answer. The 600 watts on the transformer nameplate is the maximum amount of wattage that the transformer can produce and still be within its safety limits. It doesn't draw that wattage all the time. If you had two 50 watt lamps connected to the transformer then the transformer has the capacity of 500 watts left. The transformer will only produce the wattage that the load requests. The transformer has the ability to supply twelve 50 watt bulbs. 12 x 50 = 600. Any more bulbs than 12 and the transformer is in an overload condition.
