An electric motor converts
An electric motor converts electrical energy into mechanical energy.
Overloading is due to
All are the causes to occur overloading
In Fleming’s left-hand rule the thumb indicates the direction of
In Fleming’s left-hand rule the thumb indicates the direction of mechanical force acting on the conductor. The forefinger points in the direction of magnetic field and the central finger in the direction of current flowing in the conductor.
Which among of these are the main characteristics of fuse element?
Fuse wire must have all the characteristic to prevent from a possible damage.
The phenomenon of electromagnetic induction is
Electromagnetic induction is the phenomenon due to which an induced current is set up in a coil when magnetic field around it is changed.
The main advantage of A.C power transmission over D.C power transmission over long distance iS
AC transmit over a long distance without much loss of energy as compare to DC.
The device used to produce an electric current in a circuit is called
An electric generator is used to produce an electric current in a circuit.
Earth wire carries
Earth wire carries no current.
The direction of induced current produced in a rectangular coil, when it is rotated in a uniform magnetic field, is given by
Fleming’s right-hand rule gives the direction of induced current in a rectangular coil when the coil is rotated in a uniform magnetic field.
If the current values periodically from zero to a maximum value, back to zero and then reverses its direction, the current is
The alternating current reverse its direction periodically.
