The direction of statically induced emf can be found by which law?
Lenz's Law
Which law gives the direction of induced current?
LENZ LAW gives the direction of induced current.
An electric motor has an apparent resistance 15 ohms. If 8 amps of current are flowing through the motor what is the connected voltage?
If we use the simple application of Ohm's law where voltage (E) equals current (I) times resistance (R), or E = I x R, all we need to do is plug in values. If E = I x R and I = 8 amps and R = 15 ohms, E = 8 x 15 = 120 volts.
What are the physical significance of self inductance?
According to lenz law , "effect opposes the cause " now due to flux cutting action emf induce in coil opposes the flux by which this emf is induced . So this opposition by induced current of staring current is called inductance .
Why electromagnetic torque opposes prime mover torque in dc generator?
It's a practical example of the conservation of energy, and is explained by Lenz's Law. The direction of the load current is such that its magnetic field will create a force acting in the opposite direction to the force causing the conductor to move in the first place.
Lenz's law is a manifestation of?
Lenz's Law is a part of Farady's Law known as the law of induction. It is a manifestation of the conservation of energy.
Who discovered lenz's law?
SCIENTIST: Heinrich Friedrich Emil Lenz
What is lenz's law?
The Lenz Law is "An induced electromotive force generates a current that induces a counter magnetic field that opposes the magnetic field generating the current." It was invented by a Russian Physicist named Heinrich Lenz.
What is the equation for lenz law?
The Lenz's law equation is the same as the faraday equation but Lenz found a way to predict the direction of the induced electromotive force and current from electromagnetic induction. http://en.wikipedia.org/wiki/Lenz_law
The direction of statically induced emf can be found by which law?
Lenz's Law
What is the definition of lenz's law?
conversation of energy of electromagnetic
Why lenz's law can be applied only to closed loops?
Lenz's law and Faraday's law of Induction.The induced current causes a magnetic field according to Ampere's law, which itself has a flux through the closed loop. According to Lenz's law, the direction of the induced current and which results in the induced magnetic flux opposes the initial magnetic flux.
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.'
Why Faraday's law and Lenz's law involved in generating AC current?
because its use formula from his father's law..
Which law gives the direction of induced current?
LENZ LAW gives the direction of induced current.
What would happen if the Lenz law was the opposite and the induced magnetic field pulls the magnet closer instead?
If Lenz's law were reversed and the induced magnetic field pulled the magnet closer, it would violate the conservation of energy principle. Objects would perpetually move without any input of energy, leading to perpetual motion machines, which are not possible according to the laws of physics.
What law expresses the relationship between the current in a resistor and the rate at which it produces heat?
.Faraday's Law Joule's Law Lenz's Law Ohm's Law
