Electrics & Electronics: Electrical Principles: Effects of electricity
Heating effects
 
Electricity can be transformed into other forms of energy such as the heat in head lamp bulbs.
 
Chemical effects
 
Electricity may be used to store energy through chemical reactions such as in a lead acid battery.
 
Magnetic effects
 
Sending current through coils on a shaft, in a magnetic field, draws them across the field. If the current is accurately switched, this attraction is constantly repeated to produce the rotary motion of the electric motor.
 
Electrical conduction The movement of electrically charged particles through matter.
Electrical resistance A measure of the degree to which an object opposes the passage of an electric current.
Electromagnetic field An electromagnetic field is considered to be limited to a local area around an object in space.
