In other words, the current I in amps is equal to the power P in watts divided by the voltage V in volts multiplied by the power factor PF. For three-phase AC circuits where the line to line voltage is known, the formula to convert watts to amps is:. The current I in amps is equal to the power P in watts divided by the line to line voltage V in volts multiplied by the power factor PF multiplied by the square root of 3. For three-phase AC circuits where the line to neutral voltage is known, the formula to convert watts to amps is:.
The current I in amps is equal to the power P in watts divided by the voltage V in volts multiplied by the power factor PF multiplied by 3. Wiki User. That depends on the voltage, but the residential standard is volt. Amps is an electric current unit and watt is an electric power unit.
Current is equal to watts divided by voltage. And you should never continuously load a 20 amp volt circuit to no more than watts. An electric car makes use of 4. Its electric motor rating has a mechanical input power of 50 watts. A washing machine will pull from to watts or 2. An electric dryer will pull from to watts or 7.
Watts is the product of amps x volts. As you can see, the two values are dependant upon one another. In a numerical value watts will always be higher. Electric furnaces are rated in Kilowatts. The following formula will let you figure it out. For eg. If your furnace differs from this example, just plug in your wattage and you will have your answer. Assuming a pure resistive load. About 10 to 50 amps current or to watts.
Amps are units of current, watts are units of power. Watts are the product of Amps times Volts. You cannot "convert" 9 amps in watts. Amps are a unit of electric current, and watts are a unit of electric power. To determine the power or wattage you must know both the current and voltage.
You can not simply convert amps to watts. To convert amps into watts a voltage is needed. Yes, if you know the voltage. The amperage of an electric hot water heater is governed by the wattage of the heating elements and the voltage that is applied to them.
An amp is a unit of electrical current that measures the flow of electric current. At V, it does consume 7. We live in our 5th wheel. Generators run out of gas. I was thinking about deep cycle rv batteries and solar panels to charge the batteries during the day. There are many 12v deep cycle batteries that put out AH for their 20 hour capacity. Can 12V batteries provide that amount of power? I am considering hard wiring with switch boxes a amp welding mach.
Hello Roy, it depends on the voltage. You would need a much stronger generator for amps. Hello, I have a wall baseboards heaters in my basement for a total of Watts. My breaker is 25 Amps. Can I add another Watts? Hello Serge, the voltage is V? Additional W would add the total to W and My understanding is that I would need to run amp circuits to carry this load is that correct?
Also, can you calculate the cost of electricity used in a 24hr time period. Hello Max, nice rig. You have Your understanding is correct; you will need 3 20 amp circuits. You can use our power consumption calculator here for all these calculations. Each hour, you consume Hope you can help me understand it. And now I have a device which needs W DC power.
An AC-DC power adapter has been provided and it has the following. Save my name, email, and website in this browser for the next time I comment. Table of Contents. Input Watts W. Input Volts V. Thanks Reply. Wanting to install a wind turbine watts at 12volts output how many amps at vo. Hello Charlie, W at 12V you have Thanks ruben Reply. Hello, I have a question. Is there a way to determine how many watts a 20 amp AC uses per hour?
Hi, if I have a load of Kw, V, how many amps would be sufficient? Hello, I have an inverter AC watts, v.
