Which of these best describes the flow of charge through a circuit? A
Charged particles are already present in the circuit components and they move in the same direction all at the same time.
B
Charged particles are already present in the circuit components and they move one at a time in a straight line.
C
The battery provides the charges to the circuit and they move in a straight line, one after the other.
D
None of these are correct.

Your answer is 32 hope i  

stands for electromotive force and it is measured in volts. despite its name, it is not actually the force in the sense of being a "pushing" or "pulling" (not measured in newtons).an equation that relates emf,  ℰ,  to a battery's terminal voltage, v, current, i, and internal resistance, r, is    ℰ = v + irin this case, the emf can be interpreted as a voltage—a difference in electric potential.i would not say that it would be considered an energy. if emf can be defined as the energy/work per a unit charge from a battery or other electric source, then it is not strictly energy.

Answer///(d) atoms contain small,negatively charged particles;
