Echo

The repetition of a sound resulting from reflection of the sound waves.

Echo-location

Determining the location of something by measuring the time it takes for an echo to return from it.

Echo-sounding

Determining the location of something by measuring the time it takes for an echo to return from it.

Eclipse

An eclipse is an astronomical event that occurs when one celestial object moves into the shadow of another.

Eddy-current

Circulating movement of electrical current within an electrical conductor caused by the intersection of the conductor with a moving magnetic field.

Elastic energy

Potential energy that is stored when a body is deformed as in a coiled spring or elastic band

Elastomer

Any polymer having the elastic properties of rubber.

Electric generator

A device that converts mechanical or kinetic energy to electrical energy. The reverse conversion of electrical energy into mechanical energy is done by a motor; motors and generators have many similarities.

Electric meter

A device that measures the amount of electrical energy consumed by a residence, business, or an electrically powered device.

Electrical current

Electrical current is the flow of charged electrons through a circuit. Electrical current, which is electrons flowing in a wire, can be explained as cars driving along a road, where the road is the wire and the cars are the electrons. The current would be the number of cars passing a given point.
