A device which converts electrical energy into mechanical energy is
In the second experiment of Faraday and Henry, the primary coil is connected to the galvanometer and the secondary coil is connected to a battery. If the primary coil is rotated about its axis, then:
In the second experiment of Faraday and Henry, the bar magnet is replaced with:
The experiment of Faraday and Henry explains:
In the given figure a metallic plate A is allowed to swing like a simple pendulum between the magnetic poles and it comes to rest after time t. If a slot is cut in the plate A and then it is allowed to swing with the same initial velocity as before then the time taken by it to come to rest will be:
The laminated cores are used in transformers to reduce:
During the magnetic braking of trains if the north and the south poles are replaced with each other, then the velocity of the train will:
The shiny metal disc in the electric power meter (analogue type) rotates by the:
If a galvanometer has a fixed core made of nonmagnetic metallic material, then the oscillating coil of the galvanometer comes to rest very quickly due to:
The heat gets generated in the induction furnace by:
The essential difference in design of the AC generator and a DC generator is that
The average power loss in a pure induction coil will be-
Commutator is used in:
If the frequency of the applied AC potential is increased in the R-L circuit, then the impedance of the circuit will:
Heat is generated in the induction furnace by:
