krypton

A generator is constructed by rotating a coil of N turns in a magnetic field B at a frequency f. The internal resistance of the coil is R and the cross sectional area of the coil is A. Choose the correct response for each of the following statements. True or False The average induced EMF doubles if the area A is doubled. The average induced EMF doubles if the resistance R is doubled. The average induced EMF doubles if the frequency f is doubled. The average induced EMF doubles if the magnetic field B is doubled. The maximum induced EMF occurs when the coil is rotated about the axis of t

    what about this The maximum induced EMF occurs when the coil is rotated about an axis parallel to the magnetic field lines.

    i know the curent creats for the rate of change of magnetic field. if the rate of change of magnetic field is higher then induced current will b higher
