Kj and KCal are units of energy. All energy can be measured in the same units, but that doesn't necessarily mean that you can easily convert the chemical energy in food, to electrical energy.
they both produce electricity.
When there is a heat differential between its ends
there is a relationship they produce temperature.
No single piece of metal will produce electricity when heated. You will need two different metals, mechanically touching. When the join between the metals is heated, it will produce electricity, dependant on the metals used. This is known as a 'thermocouple'.
what is a turbine and how does it produce electricity.
Thunderstorms are what produce tornadoes
Batteries do not produce electricity, they only store electricity.
It doesn produce electricity. It uses electricity and shows magnetic properties.
Electric motor
Heat is caused by resistance against electricity, or flow of current which is part of electricity. Electricity was made by physical power converted into electricity. The heat is caused by resisting the flow of electrical current.
In order to use any process to produce electricity, you need . . . - something to keep it in without it leaking out or blasting out - the ability to turn it on and off - the ability to adjust it higher and lower - the ability to get more energy out of it than it takes to run it - continuous reliable control of safety We don't have all of that for fusion yet, even though we've been working on it for around 65 years.
generators produce electricity via electromagnetic induction
