A motor-generator or a solid state power converter can do this.
A 120V power supply connected to a 30 Ohm resistor will produce 120/30 or 4 amps of current.
Yes, you can obtain 120V single-phase power from a 440V three-phase system using a transformer. By using a step-down transformer that reduces the voltage from 440V to 120V, you can safely access single-phase power. It's important to ensure that the transformer is correctly rated for the load and that all safety regulations are followed during installation. Always consult with a qualified electrician for any electrical work.
You get power by multiplying the amperes and the voltage. 12V, 10A dc would give the same power as 120V, 1A ac.
It can be if you connect two same watt lamps in series with each other. The 240 volt supply will drop 120 volts across each lamp.
Assuming you are speaking of a standard 120v AC power, a simple one-to-one isolation transformer is made for this purpose. Be sure power rating is big enough for the load.
Input would be 120v at 60hz. Standard US wall power.
You would need a 12VDC to 120VAC power supply.
Yes.
120v/12v 30amp power supply comes to mind.
Typically, a building receives two 120V lines from the power company, creating a split-phase system. These two lines are used to create a 240V supply for larger appliances and equipment within the building.
A previous member answered: "No. You will need a step up transformer to be able to use 110v appliances in 100v sockets." This is incorrect. In the US, the AC supplied to household outlets may be called 100, 110, 0r 120 Volts. These all refer to the U.S. nominal 110 Volt supply, which can range from as low as 95 volts and as high as 125 volts and most appliances labeled for 110 Volts may be used in the socket. Generally, if the plug fits, it's safe.
Theoretically that can be done with transformers, but the power available would still be limited by the circuit breaker on the original 120 v supply.
it will work but the light output will be markedly reduced.
In North America, Japan and some of northern South America, standard power supply is within 10% of 120V at 60Hz in Europe, Australia, most of South America, Africa and Asia, and New Zealand it's 230V at 50 Hz.
The Mitsubishi LT-70 turntable requires a standard AC power supply rated at 110-120V and 60Hz. It is important to ensure that the power supply meets these specifications to avoid damaging the equipment.
You can find a 120V power cable at your local hardware store. Look in the section under extension cords.
The device that operates on 120V AC power requires a power cord with a standard 3-prong plug.
