How does electric current travel?
Electric current travels through a closed circuit, flowing from a higher voltage to a lower voltage. It moves through conductive materials such as wires, where the flow of electrons creates the electric current. The rate of flow of electric current is measured in amperes.
How are electromagnetic waves usually drawn?
Electromagnetic waves are typically represented by sinusoidal waves in diagrams, where the oscillation of the electric and magnetic fields is shown propagating through space. The electric field is often shown as oscillating along one axis, while the magnetic field oscillates perpendicular to it. These representations illustrate the wave nature of electromagnetic radiation.
What energy changes are shown if the electric fan is on?
When an electric fan is on, electrical energy is converted into mechanical energy to rotate the fan blades, causing air movement. There may also be some heat generated due to the electrical resistance in the motor of the fan.
When the electric fan is on and revolving what energy changes are shown?
When the electric fan is on and revolving, electrical energy is being converted into mechanical energy as the fan blades spin to create airflow. Some electrical energy is also converted into heat energy due to resistance in the wires and motor.
What is a generated?
A generator is an electrical machine that produces electricity. It must be turned by a prime mover that can be an internal combustion engine (driven, usually, by diesel oil or gasoline), or it can be a turbine, driven either by superheated steam or by water falling from a reservoir. (The latter is known as "hydro-electric power generation.")Before today's solid-state voltage inverters were invented, electric motors were often used to drive generators to produce a different type of electrical power (for example, to produce dc power from an ac service or to produce 3-phase ac power from a single-phase ac service).For more information, see the answers to the Related Questions shown below.In electricity generation, a generator is a device that converts mechanical energy to electrical energy for use in an external circuit. The source of mechanical energy may vary widely from a hand crank to an internal combustion engine. Generators provide nearly all of the power for electric power grids.The reverse conversion of electrical energy into mechanical energy is done by an electric motor, and motors and generators have many similarities. Many motors can be mechanically driven to generate electricity and frequently make acceptable generators.
How does an electrically motor work?
An electromagnet is the basis of an electric motor. You can understand how things work in the motor by imagining the following scenario. Say that you created a simple electromagnet by wrapping 100 loops of wire around a nail and connecting it to a battery. The nail would become a magnet and have a north and south pole while the battery is connected.Now say that you take your nail electromagnet, run an axle through the middle of it and suspend it in the middle of a horseshoe magnet as shown in the figure below. If you were to attach a battery to the electromagnet so that the north end of the nail appeared as shown, the basic law of magnetism tells you what would happen: The north end of the electromagnet would be repelled from the north end of the horseshoe magnet and attracted to the south end of the horseshoe magnet. The south end of the electromagnet would be repelled in a similar way. The nail would move about half a turn and then stop in the position shown.You can see that this half-turn of motion is simply due to the way magnets naturally attract and repel one another. The key to an electric motor is to then go one step further so that, at the moment that this half-turn of motion completes, the field of the electromagnet flips. The flip causes the electromagnet to completeanother half-turn of motion. You flip the magnetic field just by changing the direction of the electrons flowing in the wire (you do that by flipping the battery over). If the field of the electromagnet were flipped at precisely the right moment at the end of each half-turn of motion, the electric motor would spin freely.
What are the difference between elactric field and electric displacement field?
The electric displacement field is a vector field, shown as D in equations and is equivalent to flux density. The electric field is shown as E in physics equations.

Can a motor supply electricity?
For some kinds of electric motors - not all kinds - the answer is yes.It is hard to explain the reasons using very simple terms, but here goes:Most small direct current electric motors that have stators which are made of permanent magnets can be made to generate direct current electricity when their rotors are turned at a fast enough speed by another engine, such as, for example, a car engine or a steam engine.For more information see the answer to the Related Question shown below.
