Which of the following best describes electric current?

What best describes an electric current?

An electric current is a flow of electric charge in a circuit. More specifically, the electric current is the rate of charge flow past a given point in an electric circuit. The charge can be negatively charged electrons or positive charge carriers including protons, positive ions or holes.

Which is the best description of current?

Current is a flow of electrical charge carriers, usually electrons or electron-deficient atoms.

How would you define electric current?

Electric current in a wire, where the charge carriers are electrons, is a measure of the quantity of charge passing any point of the wire per unit of time. … In alternating current the motion of the electric charges is periodically reversed; in direct current it is not.

What is electric current answer?

An electric current is a flow of particles (electrons) flowing through wires and components. It is the rate of flow of charge. If the electric charge flows through a conductor, we say that there is an electric current in the conductor. In the circuits using metallic wires, electrons constitute a flow of charges.

What is current in electrical engineering?

Electrical current is a measure of the amount of electrical charge transferred per unit of time. It represents the flow of electrons through a conductive material, such as a metal wire. It is measured in amperes.

IT\'S FUNNING:  Why two electric lines of force never intersect each other can two equipotential surface intersect?

How do you describe current?

Current is the rate at which electrons flow past a point in a complete electrical circuit. At its most basic, current = flow. An ampere (AM-pir), or amp, is the international unit used for measuring current.

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 is an electric current quizlet?

An electric current is a flow of electric charge. In electric circuits this charge is often carried by moving electrons in a wire. It can also be carried by ions in an electrolyte, or by both ions and electrons such as in a plasma.

What is electric current for class 10th?

Electric Current: The amount of flow charge through any cross-sectional area of a conductor in unity time is called Electric Current. Unit of Electric Current: It is CS1 (coulomb per second) or Ampere (A). Electric Current is a scalar quantity. It is measured by an ammeter.

What is electric current class 12th physics?

The rate of flow of charge through any cross-section of a wire is called electric current flowing through it. Electric current (I) = q / t. Its SI unit is ampere (A). The conventional direction of electric current is the direction of motion of positive charge.

What is electric current physics class 10th?

Electric current is rate of flow of electric charge or the amount of charge flowing through a particular area in unit time. … In reality, electric current is flow of negatively charges particles called electrons. These flow from negative terminal of the battery to the positive terminal.
