It is not dependant on voltage.
Kettles are made in various voltages. 240v in the UK, 110v in the USA and they even make 12v kettles for vehicles.
The amount of work required to boil a kettle is measured in KiloWatt/ Hours.
This value will vary depending on the amount of water in the kettle and the efficiency.
That is not possible a full kettle has more water,therefore it will take longer to boil.
A: Take 115 volts and multiply by 2.82. The frequency does not matter but he voltage does
1800 Watts at 240 volts = 7.5 AmpsIf you plugged two in, that would take it up to 15 Amps.The individual sockets are only safe up to 13 Amps, so this would be too much.So the answer is, one.Each ring main is normally fused at 30 Amps.So you would be able to plug up to 4 kettles, into individual sockets, on the same ring main.
Yes it will burn the motor in less than a minute. Use a 12 V battery to run a 12 V motor. Not exactly true. I rebuilt many engines and often to get them turned over I would use two batteries hooked up for 24 volts. The ignition was wired for 12 volts. When an engine is personally rebuilt it can be very hard to turn over. Once it runs a bit, I revert back to 12 volts. As long as you don't run the motors too long (meaning 4-6 revolutions) or to the point where they get hot, they should be fine. Electronics is another matter. Starter motors are often built with heavy wiring and can take the heat.
With enough insulation you can in theory boil any amount of water with any amount of energy, given enough time.The key is to supply more energy to the water than it looses.It takes 2260 joules to boil 1 cc of water, joules can be described at watt-seconds.One pint of water is approximately 473 cc, so that will requite 1,068,980 Joules to boil.Given perfect insulation; it would take 17816 seconds / 297 minutes / 5 hours to boil the water with a 60 watt heating element.Assuming that you do not use perfect insulation and given the fact that a peltier element won't give out all 60 watts on the one side, i'd have to say;No you can't boil a pint of water on a 60 watt peltier unit.
4 minutes 30 seconds !

The amount of electricity it would take to boil a kettle would be phenomenal, regardless of whether the kettle is made from metal or plastic. I suggest instead you try boiling the water inside the kettle first.
depends on your altitude
because it takes less time for the water to boil. I f you put more water in the kettle it will take a longer time for it to boil which takes in more energy
The more water in the kettle, the longer it will take to reach boiling point. This is why it is wasteful in energy to boil a full kettle if you only want to brew a small cup of tea.
Air pressure is higher at sea-level, so a kettle will boil quickly. Air pressure lessens the higher one climbs, so a kettle will take a long time to boil on the top of Mount Everest.

Take half cup of milk and water. Then put it in a kettle . Then keep it on gas stove . When it will boil off the gas stove. Take kettle and put it in cup . Now your tea is ready.
Because if there is nothing in it then it cant boil! The kettle will warp and not sit squarely on the burner and it might cause the finish or interior to heat up and smell horrible. Do it often enough or long enough and it'll be ruined.
