Write the equation that links current, potential difference, and resistance

Final answer: The equation linking current, potential difference, and resistance is known as Ohm's law, expressed as I = V/R, where I is current, V is voltage, and R is resistance. This can be used to calculate missing values when the other two are known. Explanation: The equation that links current, potential difference, and resistance is known as Ohm's law. This foundational principle in the study of electricity states that: I = V/R. In this equation, 'I' represents current (measured in amperes, or amps), 'V' represents potential difference (or voltage, measured in volts), and 'R' is the resistance (measured in ohms). For example, if we have a potential difference of 12 volts and a resistance of 4 ohms, using Ohm's law we can calculate the current: I = 12/4 = 3 Amps. It is given by the equation V = I × R, where V is the potential difference (voltage) across a conductor, I is the current flowing through the conductor, and R is the resistance of the conductor.

You can write the equation in 3 different ways, depending on which quantity you want to be the dependent variable.  Any one of the three forms can be derived from either of the other two with a simple algebra operation.  They're all the same relationship, described by "Ohm's Law". ==> Current = (potential difference) / (resistance) ==> Potential difference = (current) x (resistance) ==> Resistance = (potential difference) / (resistance)
