The factor, on which the frequency of an AC generator depends,
The answer provided in the forum is wrong, the correct answer would be option B and D both.
Frequency of a.c, ν=w/2π, where w is the speed of rotation
Also, frequency is defined as the number of rotations that a coil rotates in one second.
AC generator produces
Generator is a device that converts mechanical energy to electrical energy for use in an external circuit.
Which of the following is used to determine the direction of induced current in a generator?
Fleming's Right hand rule: Hold a current-carrying conductor in your right hand with thumb in the direction of the current, the direction of the field lines will be the direction of your fingers.
Efficiency of electric motor is always less than
Electric motors have an efficiency of less than 100% because there is ALWAYS energy loss through any mechanism imaginable.
Induced e.m.f is given by it will be maximum when ,
The rate of change of flux linkage is directly proportional to the induced EMF in a coil. Hence, the EMF is maximum when the rate of change of flux linkage is maximum.
