Your hair dryer has a resistance of 220/12 = Ohms. (I'm sure you can do the math.)
Probably, it's not getting any (or enough) power.CAUTION: That is a 220v 3-phase feed line and can give vicious burns and sometimes FATAL shocks.Try the following:1) Make sure that the appliance is plugged in properly.2) Reset the Circuit Breaker that feeds the appliance a couple of times.If that does not work and you have no experience working with High Voltage Electricity, Call For Service.3) Check (or have checked) the Voltage in the 3-phase plug for the drier.
Voltage is not an absolute figure. Voltage Difference is the exact term. So, the voltage difference between the two wires in the 220 V circuit will be 220V.
No, a device designed for 110v will not work on 220v without a voltage converter.
No, a device designed for 110v cannot work on 220v without a voltage converter.
You would need to use a transformer to step up the voltage from 220V to 240V. However, changing the frequency from 50Hz to 60Hz is more complicated and may require a frequency converter, which can be costly and may not be practical for a household appliance like a clothes dryer. It's recommended to consult a professional electrician before attempting to modify the electrical system.
The equation you are looking for is R = E/I.
In some parts of the world, an 1875 watt hair dryer can and does use 220 volts from a 220 volt outlet?
A 220v dryer plug typically requires a special type of electrical outlet called a NEMA 14-30 outlet.
Yes, you can.
100/220 = .45A or 450 mA
1.7amp
4 resistors were connected in parallel it yields 5A of current from 220V supply.
Yes, although you might have lucked out and tripped the breaker first.
The power-bar must be plugged into the correct voltage it was designed for.
5500Watts/220V=25 Amps
A 100 watt 220 volt light bulb (or anything consuming 100 watts on 220 volts) draws 100/220, or .45 Amps. It will also have about 220²/100, or 484 ohms resistance. A 60 watt 220 volt light bulb (or anything consuming 60 watts on 220 volts) draws 60/220, or .27 Amps. It will also have about 220²/60, or 807 ohms resistance.
Yes, it's called a step-up transformer because, if I understand correctly, you want to step up from a 110v power source to run a 220v dryer. Depending on the power (wattage) rating of the dryer, it will probably cost as much as having 220v service installed by an electrician. Furthermore, the 110v circuit must be fused for at least twice the current rating of the dryer, assuming the transformer is 100% efficient. This is because Power = Voltage x Current. If you halve the voltage (220 --> 110), you must double the current in order to maintain the same power rating. For example, if the dryer normally draws 20 amps at 220 volts, it will require at least 40 amps from a 110 volt circuit. This would require a 4000 volt-amp transformer-- a very pricey item indeed. If you opt for such a unit I would certainly consult a certified electrician.
