Yes, a simple example would be a transformer that converts one current and voltage to a different combination of current and voltage. It must be remembered however that in any action the second law of Thermodynamic requires that there be an energy loss - so you always have less energy (available for use) then what you had initially. You can also get the solution of all kind of electrical problems through Brisbane electricians. For more info. visit @Electroguru.com
Coal can't generate electricity by itself, but through the process of combustion, it can produce heat which can be used to produce steam that can run turbines which are connected to generators that produces electricity.
the island generate electricity from sae water
Using coal to generate electricity. (APEX)
An ac motor cannot generate electricity but its shaft can be coupled to that of certain devices like an alternator to in order to generate electricity.
Generate
The coal is used mostly to generate electricity.
waterfalls can generate hydro-electricity by the force of the water
We generate electricity from other forms of energy. Such as wind, sun, ect...
Acid itself cannot generate electricity. The electricity is generated by the flow of the electrons. So we can use active metal & inactive medal with acid to generate electricity. For example. If you put a copper rod and a zinc rod in acid solution (for example, HCl), connect the two rods with a conductive wire (metal wire). The the electricity will be generated because the electrons will move from the Zinc (active) rod to the copper (inactive) rod
They generate electricity produced by wind.
Muscles can generate pressure. Using transducers, pressure can be converted into electricity.
One way you can generate electricity from the sun is through a wind power plant.
