The number of turns in a coil directly affects the induced current according to Faraday's law of electromagnetic induction. As the number of turns increases, the coil experiences a greater change in magnetic flux for a given rate of change in the magnetic field, which results in a higher induced electromotive force (EMF). Consequently, a greater EMF leads to an increase in the induced current, assuming the resistance remains constant. Therefore, more turns in the coil enhance the overall efficiency of the induced current generation.
What else can I help you with?
Why the induced EMF is negative when the voltage in the first coil increasing?
It's an increasing current, not voltage, that induces an e.m.f. into a coil. The reason that the induced e.m.f. opposes the increasing current is all to do with the Law of the Conservation of Energy.
What is the difference between current coil and voltage coil?
These terms apply to the coils inside a wattmeter. 'Pressure coil' is an archaic term for 'voltage coil', which is connected in parallel with the supply, while the 'current coil' is connected in series with the load.
When a strong magnet is passed rapidly through a coil of wire what is true?
The magnetic field lines (the lines of force) around the magnet sweep the windings in the coil. This induces a voltage in the windings (through induction), and the voltage will try to drive current if it can. There is a bit more to this, but the essential elements are that the magentic lines of force cause voltage in the coil because there is relative motion between the field and the coil.
What is electrical excitability?
I think you mean 'excitation'; this refers to the process by which a current sets up a magnetic field which, in turn, induces a voltage into a conductor or coil -usually applied to transformers, motors, and generators.
How Electric power is transformed upon one coil to other coil in a transformer?
One coil builds up a magnetic field when it is energized (and de-energized) and this induces an electric current in the other coil. The voltage produced in the second coil is determined by the number of coils wound on it compared to the first coil. This is called the turns ratio and only works with alternating current unless you are using it with a dc battery to make a spark in an ignition coil. examples primary 100 turns, secondary 200 , is a step up transformer ie from 10 volts AC to 20 volts AC 100 turns primary, 50 turns secondary, step down transformer ie from 10 volts AC to 5 volts AC
How does a generator produce electric current?
A generator moves a coil of wire through a magnetic field and that induces a current in the coil .
Does a generator produce electric current?
A generator moves a coil of wire through a magnetic field and that induces a current in the coil .
When does a magnet induce an electric current in a wire coil?
A magnet induces an electric current in a wire coil when there is a relative motion between the magnet and the coil, which generates a changing magnetic field. This changing magnetic field induces an electromotive force, leading to the flow of an electric current in the wire coil.
What affects how strong an electromagnet is?
The number of turns in the coil of wire, the electrical current flowing through the coil, and the presence of an iron core inside the coil.
How does moving the magnet towards or away from the coil affect the direction of the current?
Moving the magnet towards the coil induces a current in one direction, while moving it away induces a current in the opposite direction. This is due to Faraday's law of electromagnetic induction, which states that a changing magnetic field induces an electromotive force (EMF) that leads to the current flow.
How does an electric generator generate an electric current The generator?
The rotor turns (rotates) causing magnetic fields to move across a coil of wire. This induces an electrical current in the wires of the coil.
Working principle of ammeter?
An ammeter consists of a coil with very low resistance. when electric current flows through the coil, the coil induces a magnetic field which turns the needle.
In a transformer what induces a current in the secondary coil?
The current flowing in the primary generates a magnetic field which induces a current in the secondary winding.AnswerNo current is induced into the secondary winding of a transformer. What is induced is voltage. Current will only flow in the secondary winding if it is connected to the load, and it is the load that determines the current, not the primary current.
What does a inductive ammeter do?
It measures current by creating a coil around the current carrying wire. Current flowing in the wire induces a current in the amp-meter proportional to the current flowing in the wire.
Why is current produced in a coil if it is placed near other coil containg electricity?
When a coil carrying current is placed near another coil, it creates a changing magnetic field which induces a voltage in the second coil according to Faraday's law of electromagnetic induction. This induced voltage causes current to flow in the second coil, resulting in current being produced in the coil.
Moving a magnet quickly in and out of a coil of wire produces what?
Moving a magnet quickly in and out of a coil of wire induces an electric current in the wire due to electromagnetic induction. The changing magnetic field created by the moving magnet induces a current flow in the wire loop according to Faraday's law of electromagnetic induction.
Why current flows in a coil when magnet is pushed in and out of the coil?
When a magnet is pushed in and out of a coil, it creates a changing magnetic field in the coil. This changing magnetic field induces an electromotive force (EMF) in the coil, which causes current to flow through the coil according to Faraday's law of electromagnetic induction. The amount of current flow is proportional to the rate of change of the magnetic field.
