Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge.In early days, electricity was considered as being unrelated to magnetism.Later on, many experimental results and the development of Maxwell's equations indicated that both electricity and magnetism are from a single phenomenon: electromagnetism.

Many do it yourself home renovators are unafraid to take up a hammer and saw—but balk when it comes to electrical repairs. Doing your own electrical work can be a thankfully clean task that yields to logic and science—a departure from other types of remodeling work.

This video is about electricity, not particle physics. - Power generation, how batteries work, amps, volts, ohms, are all topics I want to address in separate videos.

Likewise, electricity has a specific pressure that is regulated by the power company. This pressure allows the electrical current to flow through the wiring leading into the house and throughout the home's electrical system. Electricity is used by each electrical device or appliance.

There are three main properties that make electricity work: voltage, current and resistance. These properties work together inside a circuit, allowing electricity to move from place to place. Scientists measure voltage in units called volts, current in amps, and resistance in ohms.

Voltage from Electric Field. The change in voltage is defined as the work done per unit charge, so it can be in general calculated from the electric field by calculating the work done against the electric field. The work per unit charge done by the electric field along an infinitesmal path length ds is given by the scalar product

The electric force is a conservative force: work done by a static electric field is independent of the path taken by the charge. There is no change in the voltage ( electric potential ) around any closed path; when returning to the starting point in a closed path, the net of the external work done is zero.

Electrical Work & Repair Costs The electrical power that courses through your home is like your house's life blood. Ceiling fans, computer networks, lights, and perhaps even your heating and cooling rely on electricity to function.

Humans have an intimate relationship with electricity, to the point that it's virtually impossible to separate your life from it. Sure, you can flee from the world of crisscrossing power lines and live your life completely off the grid, but even at the loneliest corners of the world, electricity ...
