Question

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.

True False The maximum induced EMF occurs when the coil is rotated about an axis perpendicular to area A.
True False  The average induced EMF doubles if the frequency f is doubled.
True False  The average induced EMF doubles if the area A is doubled.
True False  The average induced EMF doubles if the resistance R is doubled.
True False  The average induced EMF doubles if the magnetic field B is doubled.

Explanation / Answer

True ----- The average induced EMF doubles if the frequency f is doubled.

True -----The average induced EMF doubles if the area A is doubled.

true------- The average induced EMF doubles if the resistance R is doubled.

True ----- The average induced EMF doubles if the magnetic field B is doub
