Voltage Electromotive force is represented by the upper case letter E in electrical mathematical equations like "Ohm's Law". In honor of Italian physicist Count Alessandro Volta, the measurement of the quantity of electromotive force is done with the units of Voltage; volts for short. The upper case letter V is used to represent voltage on a Digital Multimeter (DMM). If you are confused between the E and the V, you are not alone; they are often mistaken as meaning the same thing. To clarify the difference between them lets use a baking example. If a cookie recipe called for 2 cups of flour you would never confuse the measuring cup and the flour as being the same thing. The flour is what you are measuring; the cup is unit of the measurement.

Now let's compare 2 cups of flour to E and V. The E is the same as the flour; it is what you are measuring.
