How much current must flow to carry 240 watts at 120 volts?
240 watts at 120 volts requires 2 amperes. Power = voltage * current
What is the electrical voltage from the house outlet to the power supply?
The average voltage a house outlet will give actually depends on how far of a distance the house is from a transformer on the pole. If the house is fairly close to the transformer, it will probably give around 120 volts. However, if the house is a bit far from the transformer, it will probably give around 107 volts.
Can a Gateway MA465 with 120 voltage be used in a country with 240 voltage?
Typically, most adappters are rated between 120 and 240V ... it should say on the power adapter itself
What is the power voltage availble at home?
In the US, it is mainly 120-240 volts. Most appliances run on 120, with 240 being used for ranges, water heaters, clothes dryers, and large air conditioners. In Europe, much of the power is 240 volts.
Why does a hairdryer on the 240 volt setting work in the US and does this mean the switch to change the voltage is faulty and it's not really operating on 240 volts?
Hair dryers usually have a HIGH and a LOW setting. The HIGH heating element is about 8 ohms. The LOW heating element is about 32 ohms. voltage (squared) / resistance = power (watts) 120*120 / 8 = 1800 watts ( HIGH ) 120*120 / 32 = 450 watts ( LOW ) When the voltage switch is set to 240 volts, ALL it does is limit the HIGH/LOW switch to the LOW setting. 240*240 / 32 = 1800 watts ( LOW ) 240*240 / 8 = 7200 watts ( HIGH ) (the heating element would burn out)
What are the differences between a 120 volt outlet and a 240 volt outlet in terms of their electrical capabilities and applications?
A 120-volt outlet is typically used for lower power devices like lamps and small appliances, while a 240-volt outlet can handle higher power devices like ovens and dryers. The main difference is the amount of voltage each outlet can provide, with 240 volts being able to deliver more power for larger appliances.
How can I convert a 240 volt power source to a 120 volt power source using a 240 volt to 120 volt adapter?
To convert a 240 volt power source to a 120 volt power source using a 240 volt to 120 volt adapter, simply plug the adapter into the 240 volt outlet and then plug your 120 volt device into the adapter. The adapter will step down the voltage from 240 volts to 120 volts, allowing you to safely power your device. Make sure the adapter is rated for the appropriate wattage to avoid damaging your device.
How do you connect a 3 wire 120 outlet to a 4 wire 240 outlet?
You don't.
Can you use your laptop to the power outlet in UK?
Depends on the PSU, the box on the cord. If it says 120-240 volts, then you can, but you also need an adapter as the outlet itself is different.
What are the differences between electrical appliances operating at 120 volt vs 240 volt?
The main difference between electrical appliances operating at 120 volts and 240 volts is the amount of power they can handle. Appliances operating at 240 volts can handle more power and are often more efficient, but they require a different type of outlet and wiring compared to appliances operating at 120 volts.
Can you plug 120 vac to 240 watts?
'Voltage' is electromotive force, and the 'Watt' is a unit of power. You can plug a 240 watt appliance (light, toy, radio etc) into a 120 volt socket as long as the appliance is rated for 120 volt AC operation.
How much electricity in a standard outlet?
In North America 120 volts, in the UK and Europe 240 volts.
Can one leg of a 240 volt circuit be capped and the circuit breaker changed to make an existing 240 volt outlet into a 120 volt outlet?
No, you cannot simply cap one leg of a 240-volt circuit and change the breaker to convert it into a 120-volt outlet. This requires rewiring the circuit to provide 120 volts, including changing the outlet and possibly other components to be compatible with the lower voltage. It's recommended to consult with a licensed electrician to properly convert the outlet.
Will GFCI work properly if 240 volt split into one 3 wire 120 volt circuit?
No, a GFCI outlet is designed for use with standard 120-volt circuits. Attempting to use a GFCI outlet with a 240-volt split circuit could cause damage to the outlet, the circuit, and could present a safety hazard. It is not recommended to use a GFCI outlet in this manner.
Can you plug a 100 volt power tool into a 110 volt outlet?
Never heard of a power tool that runs on 100 volts AC. It would have to be 108 to 120 volts or 220 to 240 volts. It will work on the 120 volt outlet if is it 60 hertz in the U.S. or 50 Hrtz in some other countries. If it is 50 Hrtz then do not use it in the U.S. without a converter.
How do you wire a L14-30 female to 2 r-15 male plugs?
You can't do that. An L14-30 is a 240/120 outlet and you cannot "make" 240 volts from two separate plugs; you have to have a hard-wired 240-volt source (either another type of outlet or wired directly to 240 volts).
Where is the problem if you have 240V on your 120V outlet and 120V on the neutral?
Someone has wired 240 volts into your 120 volt outlet. If you have 240 volts you need a specially configured outlet so that a standard 120 volt plug cannot be inserted. If you have this situation you would see 120 volts to ground and not neutral. Sometimes if you don't look carefully an outlet will look like the standard 120 volt variety but it isn't. One of the slots is horizontal and not vertical although there may be a small vertical split. 240 volts doesn't just magically appear. What you are describing is on purpose. If it really is 120 volt receptacle you need an electrician to put in the proper receptacle or re-wire the circuit.
