Electricity

Characteristics of Ohmic and non-Ohmic Conductors

Some atoms contain loosely attached electrons. These electrons can be made to move easily from one atom to another. When these electrons move freely along a path, a current of electricity is created. Electrons can only flow freely in materials that conduct electricity. A Conductor of electricity is a substance that allows electricity to flow […]

Electrical Current

An electric current is a flow of electrical charge. When a metal conducts electricity, the charge is carried by electrons moving through the metal. Electrons are subatomic particles with a negative electrical charge. When a solution conducts electricity, the charge is carried by ions moving through the solution. Ions are atoms or small groups of […]

Electricity in Our Lives

1. Introduction Electricity means all the phenomena that result from the interaction of electrical charges. Electric and magnetic effects are caused by the relative positions and movements of charged particles of matter. When a charge is stationary (static), it produces electrostatic forces on charged objects, and when it is in motion it produces additional magnetic […]

Plight of electricity customers

According to the world nuclear association, coal is a tremendously necessary fossil used to generate electricity as well as manufacture steel. Coal combustion is however, harmful to the environment as it releases huge amounts of carbon dioxide which in turn depletes the atmosphere, more specifically the ozone layer through global warming. This translates into health […]
