Since the beginning of the universe, there has been electricity. As life evolved, electricity became an integral part of the living world. It seems as though we are constantly surrounded by electricity because for example, there's electricity in the air, there's electricity in animals, there's electricity in our bodies, and last but certainly not least, there's electricity in our homes. Electricity! Electricity! Electricity!

In the 1880s, electricity was first wired from power stations into homes, offices, and factories, in big cities such as New York, London, and Paris. So at night, instead seeing people using oil lamps or candles when you look through their 1880 house windows, you can now see how with the flick of a light switch, how people became able to turn night into day.

You can agree with me that none of the electrical appliances that we have in our various homes would be able to work without electric current moving through them. For a current to flow, there must be a circuit, or an unbroken loop, for it to travel around. There must also be a force to push the charge along, provided by a battery or generator. Current, measured in ampere, is the amount of electrical charge transferred from one place to another in a set amount of time.

Most modern houses have different electric circuits serving different needs. A main service line leads to a central distribution panel. Separate branch circuits go to wall outlets and lighting fixtures, while a heavy-duty circuit serves the kitchen and its appliances.

The question now is, how many amperes of electric current flow through a home? Because the answer to this question varies depending on the size of the home, my researched findings on this measurement ranged from 100 A to 200 A. But I did notice one reoccurring result, most private homes in the US can be adequately supported by 100 A of current.

So while there might not be one exact current value for the representation of homes, it seems that there's a general estimation of the figure. But one thing is for sure, a home is not a home without presence of electricity!
