When electric current flows „electrical work“ is produced by the impact of electrical power.

●

Energy is the ability to „do work“, therefore one speaks of „electrical energy.

●

The great importance of electricity in most every technical field stems from the diversity of the effects achieveable through electrical currents.

Some different forms of electric energy are:

►electric current produces heat, as in soldering irons and radiators

►electric current produces electromagnetic (force)fields, as in motors

►electric current produces light, as in light bulbs (incandescent light) or fluorescent tubes

►electric current causes chemical processes, as in battery packs

►electric current affects the bodies of humans and animals, as in electric shocks
