Key takeaways
State Ohm’s law for Ohmic conductors
Describe Ohmic and Non – Ohmic conductor
Use the equation for voltage, current and resistance in exam questions.
Host: Laura studied at Royal Holloway University of London and the Open University. She is passionate about science communication and has presented talks about Exoplanets at Oxford University and Imperial College London. 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 equations to allow them to excel in their future learning.
