How many watts for 60 hz?
Asked in Home Electricity
Do you have to use a transformer if your device have 900 Watts 220 V and 60 Hz with 7.5 amps?
If your device uses 900 Watts at 7.5 Amps, then it requires 120 volts. If you want to use it where the supplied current is 220 volts, then you'll need a transformer - but only if the device can operate on 50 Hz. Most places that use 220 Volts supply it at 50 Hz. If your device says it can operate on 50 Hz you can use a transformer.

How many watts can a 20 amp breaker handle?
Answer for USA, Canada and countries running a 60 Hz power supply service. Watts= voltage X amps At 120 volt total watts would be 2400 at 20 amps. The electrical code states that circuit conductors that are fed by this breaker on a continuous load can only be loaded to 80%. #12 wire rated at 20 amps, derated to 16 amps continuous = 16 x 120 = 1920 watts, #10 wire rated at 30 amps derated to 24 amps continuous = 24 x 120 = 2880 watts. On load calculations this derate should be taken into consideration. To maintain the required wattage needed for the load the wire size and/or the next size breaker may be needed.

How many amps does a hair dryer use with 25 volts 60 hz and 1500 watts?
Amps = Watts / (Volts x Power Factor). Now a hair dryer has a motor and a resistive heater so if we assume a PF = .8 the answer is: 1500 / 20 = 75 amps. Since it is unlikely that you have a 75 amp hair dryer you must mean 125 volts. The answer for that would be 1500 / 100 = 15 amps which is still high, but believable. If we assume a Power Factor of 1 and ignore the motor contribution to Power Factor we have 1500 / 125 = 12 amps.

How do you run a drill 120V AC 60Hz 4.2 amps by a battery with specs 115V AC 60Hz 100W the drill fails to turn on?
How many watts is 60 Hz 5 amps?
That depends on how much voltage is applied, because Volts x Amps = Watts. So find out your Voltage and multiply it by the amperage to get your wattage. 60Hz is standard for AC (hence the term Alternating Current) and used for long distance power transmissions and even household currents. Usually what is coming out of the socket is around 120 Volts (240 for appliances and other countries). So applying this formula to this is simple: 120Vx5A=600 Watts or 240Vx5A=1200 Watts. So on so forth... Simply multiplying volts times amps gives what's called Volt-Amperes or apparent power. Volt-Amperes equal watts (real power) in largely resistive circuits. Circuits with motors, transformers and inductors have power factors that must be taken into consideration when calculating watts. For example, in a motor circuit with a power factor .6, the watts would be Volts X Amps X .6

Will an American electrical appliance get ruined if fed 100 watts by a converter in Europe?
The amount of watts AVAILABLE to an appliance is not so significant as long as there are ENOUGH watts. Three things are important when determining what U.S. appliances can be used in Europe with converters: 1. Voltage. Most U.S. appliances operate on 110 volts. Your converter must be capable of delivering 110 volts to your appliance. 2. Current. Volts X Amps = Watts. It's a simple formula but it will determine whether your appliance will operate on a converter or just be frustrating. While volts is the "potential", Watts is a measurement of energy. It can be the energy the appliance uses or the energy that the converter delivers. If the appliance uses 200 Watts a 100 Watt converter will not work, either the appliance or the converter will fail. 3. HZ. While most appliances are not so fussy, some devices require that the electrical source be 60 HZ. Europe is 50 HZ and as such will cause some problems with appliances that require 60 HZ. FYI, HZ is the number of times per second that an electrical source reverses voltage. Commercial power is delivered as "alternating current", since that is the only way transformers can function. Europe has a different standard so make sure your appliance will operate on 50 HZ before you take it all the way over there. If the appliance does not list the energy used in Watts, it should be there in Amps, so you can use the formula above to figure out the Watts that you need. Good luck, and have a nice time in Europe.
What are the electrical abbreviations?
P = Power (Watts) E = Electrical Potential (Volts) I = Current (Amps) A = Amperage or Amps V = Volts R = Resistance (Ohms) C = Capacitance (Farads) F = Farad Hz = Hertz (cycles per second) kHz = kilo Hertz (1000 Hertz) MHz = Megahertz (1,000,000 Hertz) GHz - Gigahertz (1,000,000,000 Hertz) There are many more but this is a start

I need to replace a pond pump which says its 115v and 80hz. the newer pumps are measured in amps and watts. How can I tell from this info how many amps or watts?
I have had success with Pondmaster magnetic pumps. I suspect that your 80 Hz description is really 60 Hz. The important thing in pond pumps is how many gallons per hour you want to pump and how high you want to pump the water. Not knowing your application it is hard to size a pump for you. The 115V tells us nothing. The physical size of your pump may be a clue. You should be able to get a submersible pump for under a hundred dollars. Make sure the pre-wired cord is long enough to reach your power source.

What size wire should be used for a 2000 watt 240v electric heater?
Answer for USA, Canada and countries running a 60 Hz supply service. Wire size is based on the amperage that the device draws. To find the amperage of any device use the following equation, Amps = Watts/Volts 2000/240 = 8.3 amps. A #14 copper conductor with an insulation factor of 90 degrees C is rated at 15 amps.
