There is also a formula for power. In this formula,Pis power, measured inwatts,Iis thecurrent, measured inamperes, andVis thepotential difference(or voltage drop) across the component, measured involts. A lot of times this is also displayed as W = V * A or watts equals volts multiplied ...
Watts = Amps x Volts If the router uses 2 amps and 5 volts, its wattage would be 10W. Then, to see how much energy it uses in a day, you would then use this formula: Power (in watts) × Hours used per day ÷ 1,000 = Daily Kilowatt-hour (kWh) consumption Here’s a quick ex...
Divide the 900 W by 120 volts to get the amperage for your appliance: 900 W / 120 V = 7.5 amps. Watts, amps, voltage, and more: What do they mean? How much does it cost to power a washing machine? When you get your monthly electric bill, you only get to see the total ...
There is an unofficial standard that the power point socket should supply at least 8 amps, but many cars supply 25 to 30 amps to the socket. This will allow 300-350 watts to be safely drawn. Q: How much does a car battery weigh? How many amp-hours does a car battery contain?A:...

Generally, light bulbs use between 2 and 100 watts (W) of electricity, depending on the size and type. Traditional incandescent bulbs use 25 to 100 W, and LED bulbs use 2 to 18 W. Light bulbs draw around 110 volts and usually less than 1 amp. How much you use your light bulb has...
A home refrigerator's power consumption is typically between 300 to 800 watts of electricity, or between 3 and 6 amps and about 120 volts. Importantly, refrigerators generally have a much lower "running" wattage than their stated average wattage – this is because they cycle on and off through...
