electrical current

Electric current is the movement of electric charge carriers such as electrons having negative charge, protons having positive charge, ions (atoms that have lost or gained one or more electrons), or holes (electron deficiencies that may be thought of as positive particles) ². The intensity of electric current is usually measured in amperes.

Electric current is used in many practical applications such as charging batteries, operating household appliances like bread toasters, baking ovens, televisions and mobile phones¹. It also plays an important role in industries, transportation and communication.
