Detailed explanation-1: -An electric current is a stream of charged particles, such as electrons or ions, moving through an electrical conductor or space. It is measured as the net rate of flow of electric charge through a surface or into a control volume.
Detailed explanation-2: -In everyday use electricity typically refers to electrically charged particles (called electrons) moving through metal wires. The flow of electricity is called current.
Detailed explanation-3: -A closed circuit of conductive material provides a path for electrons to continuously flow. The charges are propelled by an electric field. We need a source of electric potential (voltage), which pushes electrons from a point of low potential energy to higher potential energy.
Detailed explanation-4: -The electric current flows through the wire due to the potential difference between the two ends. An electric field is formed in a wire when a potential difference is applied across it.
Detailed explanation-5: -Electric Current is the flow of electrons through a wire or solution. In a solid the electrons are passed from one positively charged metallic atom to next but in solution the electron is carried by the ions present in the solution. A solution capable of carrying charge is called an electrolyte.
