What will happen to the pressure difference across the rheostat? Explain. [3] Hint: calculate the pressure difference across the rheostat before and after the rheostat changes. Be sure to use the correct obstacle and flow when doing this!

The answer will be d. reflects light because it cant be all the others because light cant be other things other than light

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.
