How is voltage difference measured?

In: Consumer Electronics, Electrical Engineering [Edit categories]

Answer:

There is no such thing as a 'voltage difference'. By definition, 'voltage' is a difference in potential. So, while you can have a difference in potential, you cannot have a difference in potential difference! It's important to understand the difference between 'potential' and 'potential difference' (voltage) -in simple terms, you can equate potential to height, and potential difference to a difference in height. A value of potential depends upon its point of reference (although this is frequently measured with respect to earth), whereas potential difference is absolute.
