This resource is a complete lesson that covers Electric Fields for the OCR A Level Physics A course. However, it is useful for other exam boards too.
This lesson teaches the following content:
-electric fields are due to charges
-modelling a uniformly charged sphere as a point charge at its centre
-electric field lines to map electric fields
-electric field strength; E = F/Q
-Coulomb’s law; F = Qq/4πε0r² for the force between two point charges
-electric field strength E = Q/4πε0r² for a point charge
-the concept of electric fields as being one of a number of forms of field giving rise to a force.
This lesson includes:
-A full presentation including 4 example questions with worked solutions.
-A worksheet with model answers, perfect to set as homework.
-Clear visual aids and diagrams to simplify complex concepts.
-Editable PowerPoint and Word document for easy customisation.
