How Is Electricity

In the electric eel however currents of one ampere at.

How is electricity. Over two thousand years ago people in greece used flowing water to turn the wheel of their mill to ground wheat into flour. Bioelectricity electric potentials and currents produced by or occurring within living organisms. Hydroelectric energy also called hydroelectric power or hydroelectricity is a form of energy that harnesses the power of water in motion such as water flowing over a waterfall to generate electricity people have used this force for millennia. 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. The electricity generated is transformed into the higher voltages up to 400 000 volts used for economic efficient transmission via power line grids. When it nears the point of consumption such as our homes the electricity is transformed down to the safer 100 250 voltage systems used in the domestic market. Electricity phenomenon associated with stationary or moving electric charges.

Electric charge is a fundamental property of matter and is borne by elementary particles. In electricity the particle involved is the electron which carries a charge designated by convention as negative. Bioelectric potentials are generated by a variety of biological processes and generally range in strength from one to a few hundred millivolts.
