Electric current
(Redirected from Electric Current)
Electric current is the flow of electric charge in a conductor. It is measured in amperes and is often represented by the symbol I. Electric current can be either direct current (DC), where the flow of charge is in one direction, or alternating current (AC), where the flow of charge constantly changes direction.
Definition[edit | edit source]
Electric current is defined as the rate of flow of electric charge through a conductor. It is measured in amperes (A), which is a SI unit. One ampere is defined as one coulomb of charge passing through a point in a circuit per second.
Types of Electric Current[edit | edit source]
There are two main types of electric current: direct current (DC) and alternating current (AC).
Direct Current[edit | edit source]
Direct current (DC) is a type of electric current where the flow of electric charge is only in one direction. It is produced by sources such as batteries and fuel cells.
Alternating Current[edit | edit source]
Alternating current (AC) is a type of electric current where the flow of electric charge periodically reverses direction. It is the form of electric power that is delivered to homes and businesses, and it is the form of electrical energy that consumers typically use when they plug kitchen appliances, televisions and electric lamps into a wall socket.
Effects of Electric Current[edit | edit source]
Electric current can have several effects, such as Joule heating, magnetic fields, chemical reactions, and biological effects.
Joule Heating[edit | edit source]
When an electric current passes through a conductor, it can generate heat. This is known as Joule heating.
Magnetic Fields[edit | edit source]
An electric current produces a magnetic field around it. This is the principle behind electromagnets.
Chemical Reactions[edit | edit source]
Electric current can cause chemical reactions to occur. This is used in electroplating and electrolysis.
Biological Effects[edit | edit source]
Electric current can also have biological effects. For example, a strong electric current passing through the body can cause electric shock.
