**How to figure out a rated wattage on a motor? RC Groups**

also, some amps such as the older alpine V12's had a regulated power supply so it produced max output at 12Vdc. whereas the Phoenix Gold amps were unregulated so if you had an alternator with an adjustabe regulator you could tweat it to 15.5 ot 16VDC and squeezee more power out of the amp. Thats how the M100 was originally rated as a 20 watt amp, 10Wx2 RMS @ 4ohms @ 0.005%THD @ …... That means you can use a 1000 watt amplifier to drive that speaker -- as long as you use that power for peaks, and do not drive the speaker continuously with 1000 watts. In other words, don't turn up the amp so high that it clips.

The conversion of Volts to Amps if the wattage is known is governed by the equations Amps = Watts/Volts For example 120 watts/110 volts = 1.09 amps Converting Amps to Volts at fixed wattage The conversion of Amps to Volts if the wattage is know is governed by the equation Volts = Watts/Amps For Example, 48 watts / 12 Amps = 4 Volts Converting Volts to Amps at a fixed resistance If you know the... 15/08/2009 · From this we can work out the primary current, so in a 12v secondary the current is 5 amps, but in the 240v primary the current is .25 amps or 250 milliamps. Remember the ohms law formula 'PIE' Power = Amps(I) x Volts (E)

31/05/2009 · Watts = volts x amps so, if your motor really is rated at 36v and 750 watts, it should draw about 21A. But the problem with an electric motor is it will try to draw more amps the more load you put on it, until it's drawing so many amps that it will destroy itself and/or the speed controller how to stop cats hunting If you have two of the numbers (e.g. volts, amps) then you can find out the other (e.g. watts). This can help you to determine the rated power that you’ll need from your generator. This can help you to determine the rated power that you’ll need from your generator.

Add 3,000 watts for the two small-appliance circuits and 1,500 watts for the laundry circuit for a total of 9,900 watts. Next, add the values of all the major appliances, except the central air conditioner, for a total of 38,100 watts. how to use color box pigment stamp pad To calculate amp-hours from watts, you need to use equivalent terms: either the number of watt-hours or how long something operates at a certain number of watts. Couple this with voltage, and you can easy calculate amp-hours.

## How To Work Out Wattage From Amps

When more than 15-amps is pulled from the circuit by one or a combination of devices, the breaker in your service panel will trip, turning off the circuit as a precautionary measure. To determine the number of amps any one device pulls, you must know the wattage of the device, and the device's voltage.

- That means you can use a 1000 watt amplifier to drive that speaker -- as long as you use that power for peaks, and do not drive the speaker continuously with 1000 watts. In other words, don't turn up the amp so high that it clips.
- In order to do this calculation, you simply take the amperage (AMPS) times the voltage (VOLTS) to give you the power (WATTAGE). But we're not done yet. A 15-amp circuit that is running on 120 volts has a total capacity of 1,800 watts. To determine the safe capacity, you need to multiply the 1,800 watts times 80% to give you 1,440 watts. The rating of your motor should not exceed this rating
- Add 3,000 watts for the two small-appliance circuits and 1,500 watts for the laundry circuit for a total of 9,900 watts. Next, add the values of all the major appliances, except the central air conditioner, for a total of 38,100 watts.
- The power output of the light bulb is 100 watts. Using the equation I = P/V , we can calculate how much current in amps would be required to get 100 watts out of this 6 …
