Changes

*[[Back EMF|Back emf]] is crucial for the functioning of devices like [[motor]]s and [[Electrical Transformer|transformers]] by preventing excessive currents.

*It is a key factor in the design and operation of [[Alternating Current|AC]] and [[D.C. Motor|DC motors]].

*When an [[Motor|electric motor]] starts, the [[Back EMF|back emf]] is initially zero, allowing maximum [[Electrical Current|current]].

*[[Back EMF|Back emf]] in [[Electrical Transformer|transformers]] helps regulate the [[Electrical Current|current]] and [[Potential Difference|voltage]] during operation.
