how many amps are there in an average kettle?
912131
The average kettle is 1500-3000 Watts.\n\nA=W/V\n\nAmps = 2000/240 = 8.33\n\nSo approx 8.33 amps.

About plus and minus ten percent. That makes it 108 minimum and 132 maximum volts.\n\nMost appliances are designed to expect this range.

On nearly every appliance, there is a label, usually somewhere near where the AC cord enters the body of the appliance, or on the bottom, which states the electrical draw of the appliance.  If it is not listed in watts, then it will be listed in 'AMPS' or just 'A'.  To determine the wattage of an appliance if it gives you the draw in amps, you just need to do some simple math.  (amps) * (line voltage) = (watts).  So, if an appliance says that it draws 3 amps, and it is plugged into a standard north american outlet, which is 120 volts, then 3 * 120 = 360 watts.  If it is a 240v appliance, and draws 3 amps, then 3 * 240 = 720 watts.\n\nHope this helps...

About 2000 mL, if each cup is 250 mL

general accepted values for residential installations, for lighting branch circuits 20 amperes, for general load convenience outlets 20 to 30 amperes. for industrial is different though, normal rule is if you know how much is the total current required for that branch circuit, say for a motor load, it is approximately 120 percent for circuit breakers and 300 percent multiplying factor for fuses.  hope this will be of help.

What sort of prints? What sort of current do you want to source? How few milliviolts do you want?

Given a fixed power of heat input water would take longer due to its specific heat capacity being large.  4180Joules/kg/degree, compared with 450 for iron & 880 for Aluminium (figures STRICTLY only from memory and not to be relied on)\nOther than that are consideration of good conduction of heat in metals versus convection transporting the heat quickly within the water.\nAlso practically speaking, you might need to allow for evaporative heat loss from the water surface.

Price is a local issue depending on your utility companies. However, in tems of efficiency it's got to be electric as all of the heat in the element is converted to heat in the water and less is then lost to the surroundings through the wall of the kettle than getting a flame to externally heat the kettle. The combined cycle of the gas-electricity cycle means it would still probably be more efficient to convert the gas to electricity in an efficient electricity company generator station and then to use the resultant electricity in a home.\n\nThis can be shown quite easily- put your hand over an electric kettle and feel the excess heat being given off. Now try to do that over a gas kettle!

Heat = mass x specific heat of material x change of temperature.\nSpecific heat of water is 1. So the amount of heat needed to be added is the mass of the water x the amount of change needed to get to boiling. So cold water does not boil faster. \n\nsalt will cause it to take longer. \n\nPeople think that tea tastes betterr if you start with cold water, which holds more oxygen. As you heat the water, the oxygen comes out. This may look like boiling.

Get an electrical heating element, a DC power supply, a thermometer, a voltmeter and an ammeter.\nPass electricity through the heating element, dipped into a measured volume of water (or salt water) in an insulated cup, and measure the current, the voltage and the time taken. This will give you the heat energy supplied. Measure the temperature rise, and work out how much energy would be required to raise 1g of water (or salt water) by 1 degree Celcius. The answer should be close to 4.2!
