I found this light http://www.ecolivingcentre.com.au/products-page/?product_id=23 and it is the perfect size and power for a torch we are making in graphics, the only problem is that it runs on 240 volt ac current and the torch im going to make is going to have a 12 volt dc lead acid battery, is there any way that you can make the battery work with this light
Answer for USA, Canada and countries running a 60 Hz supply service.Use one leg of the 240v and the neutral wire. Most electric dryers run the motor this way. The heating element is 240v but the motor is 120v.NO, THAT IS DANGEROUS ADVICE because a 240 volt service has a circuit breaker which is sized for the current draw of a large 240 volt appliance, so it would have a rated amperage that is too high to protect a 120 volt motor running on its own.Only 240 volt appliances such as dryers, air conditioners, etc. are safe to use on 240 volt circuits.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
If it is a 240 volt conditioner it will stop. If it is a 120 volt conditioner it will stop if it is on the leg that has been lost.
Question is incorrect. in a 240 Volt single phase circuit, how can you have A phase and B phase?
A single phase 600 to 240 Volt transformer using two phases of the three phase primary.
Volt amps is the same way of saying watts. This is seen in the formula Watts = Volts x Amps. Using the formula I = W/E we transpose I = 20000/240 = 83.33 amps.
It will work it you use 240 volt light bulbs.
The question is "use less of what?". If they are both the same wattage the 240 V light will use 1/2 the current of a 120 V light.
Yes, you can easily use it. Just install it as you would any other 120 volt light fixture and change the bulb from a 240 volt bulb to a 120 volt bulb. It will work just fine.
One has an element designed to work on 120 volts, the other has an element designed to work on 240 volts.
Slightly dimmly
Yes, it can be connected safely but the lamp will not emit any light.
No, you will need to get a step up transformer, it's probably more sensible to get a 12v sensor.
Yes, but the lamp output wattage will be a quarter of what it is at 240 volts.power = voltage squared / resistance
yes
No, it won't get enough power and won't work.
A 240 volt street light circuit is wired in parallel connections. In the base of the street fixture an inline fuse is connected into the circuit that goes up to the fixture to protect the lamp head.
230 v appliances are made to work over a range of voltages and this includes 240 v. Usually the supply voltage can vary + or - 6% and the equipment must be designed for that. In the UK the nominal voltage is 230 v with a tolerance of -6% +10% because many or most of the outlets work at 240 v in practice.
