What is it called when current reverses at regular intervals?
An electric current that reverses its direction at regularly recurring intervals.
What are the three different types of electrical current?
They are direct current, abbreviated DC, and alternating current, abbreviated AC. In a direct current, the electrons flow in one direction.
What is the meaning of the abbreviation EMF?
electromotive force
electromotive force, abbreviation E or emf, energy per unit electric charge that is imparted by an energy source, such as an electric generator or a battery. Electromotive force is the characteristic of any energy source capable of driving electric charge around a circuit.
What is the name for the flow of electrons in an electric circuit?
Electric current
Electric current is the flow of electrons through a complete circuit of conductors.
What is meant by eddy current?
Eddy currents (also called Foucault’s currents) are loops of electrical current induced within conductors by a changing magnetic field in the conductor according to Faraday’s law of induction. The current flowing through the resistance of the conductor also dissipates energy as heat in the material.
What is the name of the effect caused by the wire when it is moved across a magnetic field?
electromagnetic induction
The process by which a potential difference is generated across the ends of a conductor when it’s moved through a magnetic field is called electromagnetic induction.
What is types of electric current?
There are two kinds of current electricity: direct current (DC) and alternating current (AC). With direct current, electrons move in one direction. In alternating current, electrons flow in both directions. Power plants produce AC electric current.
What is a conventional current?
Conventional current or simply current, behaves as if positive charge carriers cause current flow. Conventional current flows from the positive terminal to the negative. In general, analyzing an electrical circuit yields results that are independent of the assumed direction of current flow.
