===Equation===
====Equation Linking Current, Charge and Time====
''NB: You should remember this equation.''
'''Current''' = (Charge)/(time)
: This can give the definition "Current (I) is the (=) amount of [[Electrical Charge|charge]] flowing past a point (Q) per (÷) unit time (t)."
====Equation Linking Current, Potential Difference and Resistance====
''NB: You should remember this equation.''
'''Current''' = (Potential Difference)/(Resistance)
<math>I=\frac{V}{R}</math>
Where:
<math>I</math> = The '''electrical current'''
<math>V</math> = The [[Potential Difference|potential difference]] across a [[Electrical Component|component]].
<math>R</math> = The [[resistance]] of an [[Electrical Component|component]].
