1.38 C of charge flow out of a 9.00 V battery in 11.8 s. How
much resistance is attached to
the battery?
(Hint: What is the definition of current?)
(Unit = Ohm)

Ithink it is letter b, i may be wrong but i think that is the answer

Scientific classification

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.
