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.
What does an electric current mean answer?
Electric current is expressed as the amount of charge flowing through a particular area in unit time. Quantitatively, electric current is defined as the rate of flow of electric charge.
What is meant by current electricity?
Current or dynamic electricity is defined as an electrical charge in motion. … Current or dynamic electricity is defined as an electrical charge in motion. It consists of a flow of negatively charged electrons from atom to atom through a conductor in an electrical circuit.
What do u mean by electric current class 10?
Electric current is rate of flow of electric charge or the amount of charge flowing through a particular area in unit time.
What do you mean by electric current class 10?
Electric Current: The flow of electric charge is known as Electric Current, Electric current is carried by moving electrons through a conductor. … Electric current is expressed by the rate of flow of electric charges. Rate of flow means, the amount of charge flowing through a particular area in unit time.
What does electric circuit mean?
electric circuit, path for transmitting electric current. An electric circuit includes a device that gives energy to the charged particles constituting the current, such as a battery or a generator; devices that use current, such as lamps, electric motors, or computers; and the connecting wires or transmission lines.
What is current discuss?
Current is a flow of electrical charge carriers, usually electrons or electron-deficient atoms. The common symbol for current is the uppercase letter I. … One ampere of current represents one coulomb of electrical charge (6.24 x 1018 charge carriers) moving past a specific point in one second.
What causes electric current?
Electricity is created when an outside force causes electrons to move from atom to atom. The flow of electrons is called an “electrical current.” … Voltage is the “outside force” that causes electrons to move. Voltage is potential energy.
What do you mean by electric current Class 7?
An electric current is a flow of electric charge. This electric charge is carried by moving electrons(charge carriers) in a wire. Electric current is measured as rate of flow of charge. The SI unit for measuring an electric current is the Ampere (A). Electric current is measured using a device called an Ammeter.
What does an electric circuit mean Ncert?
What does an electric circuit mean? Ans. A continuous conducting path consisting of wires and other resistances and a switch between the two terminals of a cell or a battery along which an electric current flow is called a circuit.
