which factors determine the amount of electric current in a circuit?
switch
ammeter
voltage
resistance

So, voltage (U) and resistance (R) are linked with current (I) by the equation , that THE basic law of electricity. Onther two things mentioned are a component (switch), a mechanical part, and an instrument (ammeter), that is used to measure the current, but does not change or control it. The answer is Voltage and Resistance.

Scissors and a seesaw both cut things that’s the only comparison

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.
