ELECTROLYSIS
DEFINITION OF SIMPLE TERMS Electrolysis – Is the process whereby a liquid conducts electricity by the movement of positive and negative ions within the liquid while undergoing chemical changes. Electrolytes – Are liquid, which allows the electricity through them is…
ELECTRIC CELLS
ELECTRIC CIRCUIT Electric current is simply electric charge in motion. Electric cells are chemical devices, which are capable of causing an electric current to flow. This produces electric force, which pushes the current along. Electrons flow from the negative terminal…
ELECTRIC FIELD
An electric field is a region of space which surrounds a system of electric charges. Electrical forces will act on any electric charge which is placed within the region. Electric field is a vector quantity. The direction of the filed…
GRAVITATIONAL FIELD
INTRODUCTION Gravitational field is a region or space around a mass in which the gravitational force of the mass can be felt. Gravitation is the force of attraction exerted by a body on all other bodies in the universe. Gravitational…
