Does an inductor absorb electrical energy?
Yes, both capacitors and inductors are capable of storing energy. Capacitors store electrical energy in form of electrical charge and inductors in form of magnetic field. - Neeraj Sharma
How inductance is produced when electric current passes through a conductor?
Electric charges interact with changing magnetic fields. All magnetic field changes can be thought of as the magnetic field moving. If the magnetic field strength is increasing then it is the same as a magnet being brought nearer while a decreasing magnetic field is the same as if a magnet is being pulled away.The force a charge experiences is the result of several factors. The direction of the force depends on the polarity of the charge, whether it is positive or negative, the direction of the magnetic field and the direction of relative motion between the charge and magnetic field. The magnitude of the force, its strength, depends upon the amount of charge, the strength of the magnetic field and the speed of the relative motion between them.So you can make charges inside a piece of wire move by waving a magnet near the wire. If the wire makes a circuit, then you get electric current flowing through that circuit. A generator is a device which uses the interaction between charges and changing magnetic fields to create electric current. Generators require a source of mechanical energy to run. Portable generators typically use gasoline while generators used by the electric power company can be driven by water, wind, coal, natural gas or the heat from nuclear fission. Coal is the most common source of energy for electricity in the United States.
WHY It is easy to convert an AC to a higher or a lower voltage with transformers?
AC current is constantly alternating between moving back and forwards, this maintains a changing electromagnetic field around it. This principle is used to power a AC transformer, which is made of very simple materials (copper wire and a lil bit of iron usually) and has no moving parts. DC current is moving all in the same direction. This creates a static field as no change is occurring. Transformers rely heavily on that changing magnetic field to carry out induction and change voltages, DC power was historically put through a commutator or later an Interrupter to create movement in the magnetic field. A commutator is the active element in little electric motors that makes them spin and an interrupter is similar to those old school morse code devices that pulses (switches on and off rapidly) the DC signal to create a field travelling up and down. Once the filed has some movement in it, it was sent into an AC transformer and then converted back. The process has evolved since then, but is still reliant on a changing magnetic field.
Why use capictor in motor?
To create rotating magnetic field inside motor stator and it is done by capacitor. current drawn by motor running winding is lagging in nature when capacitor is connected in series with starting winding then the phase angle of running winding current and starting winding currents changes which creates a rotating magnetic field and motor is able to run.
What is Inductor transient response?
An inductor resists a change in current through the creation/destruction of the magnetic field around the inductor. In an IR Circuit, when the electromotive force (the battery voltage) changes, the inductor will create a voltage to oppose the change, causing the current flowing through the circuit to change gradually over time rather than instantaneously. In an ideal IR circuit, the induced voltage is initially equal and opposite to the change in electromotive force, and it decays exponentially, with a time constant proportional to the inductance of the circuit.
Why the output voltage from a transformer is zero if a direct current flows through the primary coil?
A transformer relies on AC current flowing through the primary to set up changing magnetic fields in the core. The field flows through the core and in to the secondary of the transformer, generating an AC current. The current must be AC, otherwise the magnetic field in the core of the transformer will saturate. In the same way, the armature of a dynamo or alternator must be moving in order to create a changing magnetic field to create current through the windings.
When an electric current is passed through a coil what does this create?
A magnetic field.
What do moving electrical charges create?
-- Electric charge that's moving is the definition of electric current.-- It creates a magnetic field in its neighborhood.
When a electric current flows through a wire it creates a?
When an electrical current flows through a wire it creates what is called an Electro Magnetic Field.A magnetic field is create when an electric current flows through a wire.
Does electric current create magnetic fields?
Yes, electric current does create magnetic fields
What happen to magnetic compass if the current is changed?
If an electric current flows through a wire, it will create a magnetic field. ... a ship or an airplane, it can damage or otherwise change the ship's magnetic compass.
Can a moving electric charge create a magnetic field?
Yes. A spinning charge will create a magnetic field as will a moving charge.
What creates a magnetic field?
Both magnetic materials and moving electric charges induce magnetic fields. "A magnetic field can be created with moving charges, such as a current-carrying wire. A magnetic field can also be created by the spin magnetic dipole moment, and by the orbital magnetic dipole moment of an electron within an atom." A magnetic field can be produced by either a permanent magnet, or an electromagnet, the latter requiring suitable energization to function.
A device that produces a magnetic field by an electric current?
Any device with an electrical current will create a magnetic field. A tube of wire coils with a current running through it is called a solenoid and it will produce a magnetic field through the inside of the tube, as well as around it... Sorry, not much for physics.
Who discovered that electric current going through a wire can create a magnetic field?
Hans Christian Ørsted
What is the Field due current flow through a conductor?
Circular magnetic field will create around the conductor.
How is a magnetic force in an electromagnet created?
An electromagnet uses electricity to create the magnetic field. Moving charges create magnetic fields. Knowing that, if we have a lot of copper wire (with a suitable insulator) wrapped around an iron core, we can send direct current through that wire, and it will create a magnetic field. The magnetic field will magnetize the iron core, and the core becomes a magnet. Wrapping wire around a nail and connecting a battery to the ends of the wire will make a simple electromagnet.
