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 or FALSE 1. The average induced EMF doubles if the area A isdoubled. 2.The average induced EMF doubles if the frequency f isdoubled.
3.The maximum induced EMF occurs when the coil is rotatedabout an axis perpendicular to area A.
4.The average induced EMF doubles if the resistance R isdoubled.
5.The average induced EMF doubles if the magnetic field Bis doubled.
