110V and 120V are essentially the same thing--don't worry about that.
50 Hz vs. 60 Hz is more important, for some devices.
North America is 60 Hz; much of the rest of the world is 50 Hz.
What else can I help you with?
240V to a standard outlet?
You cannot plug a 240V appliance directly into a standard 120V outlet as it can cause damage or be a safety hazard. You would need a dedicated 240V outlet and possibly a step-down transformer to safely use the appliance. It's recommended to consult an electrician for proper installation.
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
How much power will a 230v adapter pull from a 120v outlet?
Power is multiplication of voltage and current. You need to know the load current drawing to establish the power. It is a bad idea to use 230 v adapter in 120 volts outlet
Can you use 120V lamps in Europe by just putting in a 240V bulb and a European adapter on the plug?
If all the components are rated to 220V, yes. Keep in mind that if the appliance was designed for 110V it may arc if 220 is run through it. If you don't know the device can handle 220V, don't run it at 220V. Chances are it was manufactured cleaply and cannot handle the extra voltage.
How do you get a 110V outlet in a car?
You will need to purchase a power inverter. An inverter changes direct current, like what is in your car, to alternating current, like in a home. You will need to know the wattage of the item you are powering in order to buy the correct sized invertor.
If I hook up an electrical device that requires 100V 500W with a transformer that outputs 110V 500W will this cause a problem?
No. But I am interested to know what the primary voltage to the transformer is.
How many amp in 110v?
To determine the number of amps in a 110V circuit, you need to know the wattage (power) being used. The formula to calculate amps is: Amps = Watts / Volts. For example, if you have a device that uses 1100 watts, it would draw 10 amps (1100 watts / 110 volts = 10 amps).
How much does an accountant get an hour?
if i have 120v and 3hp i need know watts
How do you know where the high end or low end of your cars ac unit is?
The high pressure (discharge) side starts at the compressor outlet and ends at the metering device inlet. This side will have the smaller refrigerant lines. The low pressure (vacuum) side begins at the metering device outlet and ends at the compressor inlet. This side will have the larger refrigerant lines.
Need to buy a 220V clothes dryer and plug into a 110V outlet A can an electrician rewire or B will a transformer work and C know it will be inefficient but will it be safe?
This isn't an answer- it's from the questioner :) Just to clarify: This is the small, apartment-sized, stacked washer-dryer unit. They used to commonly come in 110V. They are still out there but old and sell for same price used as the used newer 220V. So we'd like to buy a newer used 220V and convert if possible and safe. Don't know the watts on these, tho. But must not be as large as regular sized dryers?
How many watts does it take to run a heat mat?
I don't know what exactly you mean by a "heat mat", but your question is kind of backwards. You don't run an electrical device *with* watts. You run them to *produce* watts (watts of light, watts of heat, watts of sound, etc). I believe the thing you are really asking is how many amps are required to run your device. As an example, consider a "1500 Watt heater" that is made to be plugged into a typical wall outlet in your home. The voltage in the wall is 120V, and the heater will produce 1500 watts of heat when plugged into that 120V. To calculate the amps, you divide the watts by the voltage. 1500W / 120V = 12.5A
Is there an electrical switching device for residential use that will either run the furnace or the air conditioner to avoid increasing electrical service size?
A $10 120v or 24v relay tied into the controls of both units will do it, if the electrician is smart enough to know how to wire it in.
