An emf source is defined in terms of:
A) the force it exerts on charges
B) the work it does on charges
C) the electric field it generates
D) the current it generates
E) the charge it emits
Homework Answers
Emf is nothing but the energy supplied to the charge or work done on the charge.
$$ \mathrm{Emf}=\mathrm{dW} / \mathrm{dq} $$
so, option B is correct answer.

Theory Electric field is a measure of the degree to which a source charge Q distorts its surrounding space. As a result of this distortion, the motion of other charges q are driven by the electric force Fe the source charge exerts on them. In this regard, electric field is defined as the ratio of the force (which the source charge Q exerts other charge q) to charge q: F Ē 9 The direction of electric field at a point...
