      Background Information: Ohm's Law



      Ohm's Law is the relationship between voltage current and resistance. Resistance is measured in Ohms and the higher the Ohms the higher the resistive value.

      Ohm's law equation is defined by: V = I X R.

      Whereby; V (Potential Difference in Volts), I (Current in Amps) and R (Resistance in Ohms)

      This formula can be mathematically rerranged to calculate the voltage, current or resistance value.
