a moving coil and moving magnet
A magnet created when electric current flows through a coil of wire is called an electromagnet.
It is not true that when electric current flows through a long conductor each electron moves through a relative short distance because electric current is the continues flow of electrons.
Alternating current flows through a flat iron.
Electric current is the rate of [http://hyperphysics.phy-astr.gsu.edu/hbase/electric/elecur.html#c2 charge] flow past a given point in an electric circuit, measured in Coulombs/second which is named Amperes through any cross sectional area,which can be measured by Pi*r*r. [1coulomb/second=1Ampere]while Electric current density is the measure of electric charges passing through a conductor in a electric circuit in a constant cross sectional area of 1 meter square.[1Ampere/Meter square]
We know specifically the definition of current density as current flow through a surface of unit area. Conduction current is the current through the conductors in the presence of electrostatic fields and displacement current is the current flow due to time varying electric fields
Electric current from a generating plant is typically referred to as electricity or power. It is the flow of electric charge through a conductor, such as wires, that can be utilized to power various devices and systems.
Electric current from a generating plant is typically alternating current (AC), which flows back and forth in a rapid and regular manner. This AC current is then transmitted through power lines to homes and businesses for use in electrical appliances and devices.
In a generator, mechanical energy is converted into electrical energy. This process involves the rotation of a coil of wire within a magnetic field, inducing an electric current to flow through the wire and generating electricity.
When a wire loop in a generator rotates within a magnetic field, it cuts through magnetic field lines, inducing an electric current in the wire due to electromagnetic induction. This phenomenon is the basis for generating electricity in power plants, where mechanical energy is converted into electrical energy.
A semiconductor device that produces electric current through the photo-voltaic effect is a solar cell. When sunlight shines on the cell, it creates an electric current by releasing electrons from the material. This electric current can then be harnessed for various applications, such as generating electricity for homes or powering electronic devices.
Components such as resistors, capacitors, and inductors can affect electric current by either impeding the flow (resistors), storing charge (capacitors), or inducing voltage (inductors). These components change the overall characteristics of the circuit, affecting the amount of current that flows through it.
An electric current must flow through the coil of wire to make the electromagnet work. This current creates a magnetic field around the coil, inducing magnetism.
An electromagnet is made by an electric current flowing through wires. The magnetic field is created when the current passes through the wire, generating a magnetic field around it. This magnetic field can attract or repel other magnetic objects nearby.
An electrical current will cause an electromagnet to energise.
When an electric current passes through a wire, the wire gets hot because the flow of electrons in the wire encounters resistance, which causes the electrons to collide with atoms in the wire, generating heat as a byproduct of this interaction.
The English scientist, Michael Faraday. He invented the first dynmos and electric motors after experimenting with inducing magnetism by passing current through conductors.
The electromagnet in an electric motor is typically called the rotor or the armature. It is the part of the motor that rotates when an electric current is passed through it, generating mechanical energy.
