In the electrical circuit the higher the voltage the lower the?
Amps Ohm's law states the current is directly proportional to the applied emf (voltage) and inversely proportional to the resistance of the circuit.
If the decrease voltage and the resistance stays the same is current increased or decreased?
This question follows Ohm's law which states, "Current is directly proportional to the applied EMF (voltage) and inversely proportional to the current in the circuit. <<>> decreased
What is ohm low?
v=ir Ohm's law states that , in a dc circuit the current is directly proportional to the applied voltage and inversely proportional to the resistance at a constant temperature. It has the formula V=IR where I is the current and R is the resistance.
If power is constant increasing the voltage will increase or decrease current?
Decrease, because W = I (current) x V (voltage), if one increases, the other decreases in proportion to the increase of the other. Ohm's Law states current is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit.
Working principle of generator?
An electric generator is a device which converts mechanical energy to electric energy. An electric generator basically works on two principles, they are:- 1. Electro magnetic induction: This was first discovered by Michael Faraday this law states that when a electric conductor moved through a magnetic field cutting the electro magnetic waves, a electric charge is produced in the conductor. 2. Flemming's right hand rule: Place your thumb finger, index finger, and your middle finger in such a way that all the three are mutually perpendicular to each other. Here if your thumb points the thrust or force and index finger points the electro magnetic field then your middle finger points the direction of induced current. An electric generator consists of a electromagnet or a huge horse shoe magnet in which an armature is enclosed. The armature is made of copper coils. Now when the armature is rotated, it cuts the electro magnetic waves generated by the magnet and hence as a result of electro magnetic induction electricity is generated in the armature and the direction of the induced current can be found out using the Flemming's Right Hand Rule. And how the electric current produced later is stored and carried out differentiates between AC generator and DC generator
Which law states that voltage is induced in a circuit whenever the flux linking the circuit is changing and that the magnitude of the voltage is proportional to the rate of change of the flux linkage?
Faraday's law of electromagnetic induction states that a voltage is induced in a circuit whenever there is a changing magnetic field that links the circuit, and the magnitude of the induced voltage is proportional to the rate of change of the magnetic flux.
What is Faraday's 1st law?
Faraday's 1st law of electromagnetic induction states that a change in magnetic field within a closed loop induces an electromotive force (emf) in the loop. This emf is proportional to the rate of change of the magnetic field with respect to time and is the basis for generating electricity in devices like generators and transformers.
What is the relation of conductor velocity?
The conductor velocity is directly related to the induced voltage in a conductor moving through a magnetic field. This relationship is described by Faraday's law of electromagnetic induction, which states that the induced voltage is proportional to the rate of change of magnetic flux through the conductor.
What is the concept behind electromagnetic induction?
Electromagnetic induction is the process where a changing magnetic field induces an electric current in a conductor. This phenomenon is described by Faraday's law of electromagnetic induction, which states that the induced electromotive force in a circuit is directly proportional to the rate of change of the magnetic field flux through the circuit.
What effect does the speed of the rotating loop have on the generated electric current?
The speed of the rotating loop affects the rate at which magnetic field lines are cut by the loop, resulting in a higher induced current when the speed is increased. This is due to Faraday's law of electromagnetic induction, which states that the induced electromotive force (EMF) is directly proportional to the rate of change of magnetic flux through the loop.
What is stated by the law universal of gravitation?
The Law of Universal Gravitation is derived from observations by Isaac newton, called induction. It states that, "Any two bodies in the universe attract each other with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them."
What is the formula in electromagnetic induction?
The formula for electromagnetic induction is given by Faraday's law, which states that the induced electromotive force (emf) in a closed loop is equal to the negative rate of change of magnetic flux through the loop. Mathematically, it can be expressed as emf = -dΦ/dt, where emf is the induced electromotive force, Φ is the magnetic flux, and t is time.
What law states that emf is enduced in a loop of wire is proportional to the rate of magnetic flux through the coil?
That is Ampere's law. The emf in a loop is proportional to the rate of change of the magnetic flux.Mathematically Curl E = -dB/dt and the emf comes from applying Stokes's theorem to the surface integral of B.
What is Farady's law?
Three laws of electromagnetic induction, and two laws of electrolysis, all proposed originally by English physicist Michael Faraday. The laws of induction are: (1) a changing magnetic field induces an electromagnetic force in a conductor; (2) the electromagnetic force is proportional to the rate of change of the field; and (3) the direction of the induced electromagnetic force depends on the orientation of the field. The laws of electrolysis are: (1) the amount of chemical change during electrolysis is proportional to the charge passing through the liquid; and (2) the amount of chemical change produced in a substance by a given amount of electricity is proportional to the electrochemical equivalent of that substance.
What is lenz law of electromagnetic induction?
Lenz's law states that 'for a current induced in a conductor by a changing magnetic field, the current is in such a direction that its own magnetic field opposes the change that produced it.'
What are the factors that determine the amount of induced current?
The factors that determine the amount of induced current in a coil include the rate of change of magnetic flux through the coil, the number of turns in the coil, and the resistance of the coil. Faraday's law states that the induced electromotive force (emf) is directly proportional to the rate of change of magnetic flux.
How does electric induction occur?
Electric induction occurs when a changing magnetic field induces an electric current in a nearby conductor. This phenomenon follows Faraday's law of electromagnetic induction, which states that the rate of change of magnetic field induces an electromotive force (emf) in a closed circuit. This induced current can then power electrical devices or be used for various applications.
