It is the complex ratio of the voltage to the AC (alternating current) circuit. It extends the concept of resistance to AC circuits due to magnitude and phase.
A 'load' is a device that does work by using electricity. 'Load' can also refer to the amount of electricity used.
Current is the rate of flow of electric charge.
William Gilbert is called the father of modern electricity. Some refer to Benjamin Franklin as the father of modern electricity but William is considered the first father.
Electricity , or in this case we refer to charge, is always trying to move from conductor to conductor. Whenever it stays still and the charge can't go on to anything else it is called static electricity. This is how it normally acts.
I think this must refer to direct water heating rather than production of electricity
I don't know of a formal name, but in the trade we refer to it as a "switchgear bank".
Yes, these terms refer to the same thing. A storage battery is a means of storing electricity.
Conduction may refer to the transfer of either heat or electricity.
Electricity was not "invented". It is a natural phenomenon which is around us in nature. The real question is how it was discovered and how it was first contained, or controlled. To see more information, refer to the related question below.
Yes, hydro power and hydroelectricity refer to the same thing. It is electricity generated by harnessing the energy of moving water using turbines in hydroelectric power plants.
Rather than type out a long list, I refer you to the NRC website, see below
We use the term insulator, specifically electrical insulator, to refer to an object or material that does not conduct electricity to any significant degree.The term insulator, with no other explanation, is assumed to refer to electrical insulators. There are of course other materials which are used as insulation for heat. They provide thermal insulation and may or may not conduct electricity.
