Eddy currents - small induced currents in a conductor where the flux is changing that dissipate energy

Efficiency - the ratio of useful work or power to input work or power

Elastic potential energy - the energy stored in a spring when it is compressed or stretched

Electric charge - a conserved property ot matter

Electric field - the field produced by electric charges

Electric field strength - the electric force per unit charge experienced by a small point positive charge

Electric potential - the work done per unit charge by an external agent in bringing a small point positive charge from infinity to a point

Electric potential energy - the work that needs to be done by an external agent in order to bring a set oi charges horn where they were separated by an infinite distance to their current position

Electric resistance - the ratio of the voltage across a device to the current through it

Electrical energy - same as electric potential energy
