Thanks for the replies, however, aren't we suppose to extract information that is provided by the question?
How do you guys deduce the answer from {E_c} = \frac{{d\Phi }}{{dx}} ?
Homework Statement
The e.m.f E of a battery is given by E = \frac{P}{I} where P is the power supplied from the battery when current I flows through it. An e.m.f. {E_c} can also be induced in a coil when the magnetic flux, \Phi , associated with it changes with time, t, as expressed by {E_c} =...
