Potential Difference

Many Circuits use a change in the potential difference to operate certain chips and functions. Potential difference is achieved by connecting two resistors in series. The difference is then worked out by the formula (R2/(R1+R2))*V with R1 being the top resistor and R2 the bottom one.
