What number does a bit that is turned on represent? what number does a bit that is turned off represent?

In digital electronics, only two numbers are used to represent the state of the bit. These two numbers are "0" and "1" where:

- The bit that is turned on is represented by the number "1" 
- The bit that is turned off is represented by the number "0" 

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.
