Verified Answer
The EMF equation e = NωrΦsinωrt is applicable to _____...
e = NωrΦsinωrt-NdΦ/dtcosωrt, for time invariant field flux dΦ/dt = 0 ⇒ e = NωrΦsinωrt, is the general equation, and is applicable to both AC and DC systems.

The EMF equation e = NωrΦsinωrt is applicable to _____...
DΦ/dt, where e is the induced EMF (electromotive force), N is the number of turns in the coil, and Φ is the magnetic flux, describes the relationship between magnetic fields and electric fields in a coil. The equation states that the induced EMF in a coil is directly proportional to the rate of change of magnetic flux through the coil. This relationship is the basis for the operation of generators, transformers, and other electrical devices that rely on electromagnetic induction.
