Who is discovered motor?
As a motor refers to the electric verison (petrol is an engine) the first commutator-type direct current electric motor capable of turning machinery was invented by the British scientist William Sturgeon in 1832
Differentiate parallel circuit and siries circuit?
If two circuit elements (e.g., two resistors) are in series (a series circuit), the current has to pass first through one, then through the other. If they are in parallel, the current has a choice, through which of the elements it passes.
What is the reason behind the lag of current in inductor lead in capacitor?
The physics of the energy storage. In an inductor, the current must fight against the stored energy in the magnetic field which tries to keep the current unchanged. Any change in the current lags the voltage since the stored energy impacts the adjustment. Similarly, the "displacement" current in a capacitor leads the electric field buildup in a capacitor, causing the voltage to lag the current until the stored energy building up in the electric field stabilizes. Any change in the voltage is first preceded by a change in the displacement current.
Does adding electric currents to something that is already magnetized increase or decrease the power of the magnet?
By 'adding electric currents', you are presumably talking about passing a d.c. current through a coil wound around a magnet?First of all, you cannot increase the flux density of a magnet beyond saturation, regardless of the current or number of turns that make up the coil. Whether on not you increase or reduce the flux density depends on the polarity of the coil compared with the polarity of the magnet; if they are opposite then, yes, you can demagnetise the magnet and, in fact, remagnetise it in the opposite direction.
If two bulbs in a series are connect to a battery and the current in the first bulb is found to be 1 ampere then what is the current through the battery?
A circuit with a 2 ohm resistor and a 4 ohm resistor in series with a 12 volt battery will have 2 amps flowing through each resistor. The current is the same in each resistor because they are in series, and a series circuit has constant current throughout.
Who discovered electromagnetic force?
Hans Orsted first discovered that when an electric current was run through a wire and put close to a compass, the needle moved toward it. Although, he had no idea what that meant. Michael Faraday, built on his work and found that when an electric current runs through a wire, a magnetic field is produced around the wire. He also found that an electric field is around a wire it produces an electric current. The direction of the current depends on which direction the field is going in. The faster you move the electric field the stronger the current.
Who discovered that the electric current flows at the speed of light?
A german physicist named Gustav Robert Kirchhoff was the first scientist to show that eletric current flows at the speed of light through a conductor.
Where does electricity get energy?
An electric current HAS energy. The energy comes from whatever caused the electric current to flow in the first place - for example, a generator, or a battery.
What is electric current in which current flows first in one direction and then another?
Alternating Current could fit this description in this question.
Process of producing an electric current in a loop of wire by either moving a magnet through the loop or moving the loop through the magnet?
This process is known as Electromagnetic Induction first observed by Michael Faraday.
How can electric current change?
In order to change an electric current, you must first change the conductor, doing so will change the flow of atoms which will change the electrical discharge.
How are electric currents and magnetism related?
Magnetism could be produced due to the flow of electrical current. This was first discovered by Oersted. By changing the magnetic flux linked with a coil electric current could be induced. This was first studied by Michael Faraday. Just due to the orbital motion or spin motion of electron magnetism is produced in tiny form and is known as magnetic dipoles. Such dipoles getting oriented in different form lead to form dia, para and ferro magnetic materials.
Consider two identical resistors wired in series one behind the other If there is an electric current through the combination the current in the second resistor is?
Two resistors wired in series (no mater if they have the same resistor value or not) will always have the same amount of current flowing through them. Therefore, the current flowing through the second resistor will be equal to the current flowing through the first one. The current through every component in a series circuit is the same. The voltage across every component in a parallel circuit is the same.
How can the flow of electric current be started and stopped?
In order to change an electric current, you must first change the conductor, doing so will change the flow of atoms which will change the electrical discharge.
Who discovered how to make electricity in 1831?
The English scientist, Michael Faraday. He invented the first dynmos and electric motors after experimenting with inducing magnetism by passing current through conductors.
What type of magnetic field will produce an electric current in a wire?
A current carrying wire has a magnetic field around it but no electric field.There will be electric field around a body only if it has static electricity.In this wire, charges(electrons) are moving.The number of charges entering is equal to number of charges leaving the conductor.So it remains neutral.A neutral body cannot have an electric field around it. ACTUALLY, there IS also an electric field. A current is made up of moving charges, and all charges (moving or static) create an electric field. Materials that have a neutral charge are not good conductors and therefore would not have a current going through them in the first place.
What is the difference in parallel circuit and series circuit?
In a series type circuit, the electric current passes through each element of the circuit (light bulb or whatever) in sequence; it does not reach any element until it has first passed through all the earlier elements. In a parallel type circuit, every element of the circuit receives its electric current independently. A separate wire connects each element to the source of the current rather than to the previous element of the circuit.
