How many amps does an iron pull?
A typical iron pulls around 9-12 amps when in use. It's important to check the specific amp requirement of your iron to ensure it matches the capacity of your electrical circuit.
What has more power a 5 amp grass trimmer or a 18 volt one?
At a specific voltage the higher the amperage the higher the rated horsepower of the motor. You will see the amperage rating used when manufactures sell hand tools. A saw that draws 12 amps, it is stated, is better than the saw that draws 9 amps. As the question stands a comparison can not be made between voltage and amps.
How do you work out 9 volts and current 0.02 amps?
To calculate power, multiply voltage (9 volts) by current (0.02 amps): 9 volts * 0.02 amps = 0.18 watts.
Can you use a standard outlet for a sauna that requires 120v2035w20A?
A standard home outlet in North America is 15 amps protecting a #14 copper conductor. The circuit should only be loaded to 80% of the circuits capacity. Watts = Amps x Volts = 15 x 120 = 1800. 1800 x .80 = 1440. As you can see a standard outlet does not meet the requirements, with or without the de-rate factor, that the sauna manufacturer recommends. The amperage that the sauna needs is, Amps = Watts/Volts. Amps = 2035/120 = 16.9 or (17 amps). The circuit for the sauna would require a single pole 20 amp breaker feeding a #12 copper conductor which is rated for 20 amps. The amperage rating of the sauna is just over the 80% by .9 of an amp. This amperage is close enough that it would be passed by an electrical inspector if this project were to be inspected.
How many 9 watt bulbs can an 14 amperes 12 volt battery support?
Batteries are normally specified in ampere hours. A 12 v battery could be specified as 14 A-h or 14 ampere-hours, which means 14 amps for 1 hour, or 1.4 amps for 10 hours. In other words it produces less current for a longer time. A 9 watt bulb takes ¾ amp in theory, so it should last 14/¾ hours on that battery, that is 14 x 4 / 3 hours, 18 hours. Or two of the same bulbs for 9 hours, etc.
