Solving equations and formulas are an essential topic to grasp in Physics. In this class we will look at Ohm’s law that relates current, resistance and potential difference (voltage). We will rearrange the equation and apply it to Ohmic conductors, whilst discussing how non -Ohmic conductors behave.  These 5 minute, short burst classes give students the chance to practise solving the equations and allows them to excel in their in future learning.
