Electric Circuits - Introduction [IB Physics SL/HL]

This video provides an overview of the concepts required to understand electric circuits from Theme B of the IB Physics SL & HL courses. After introducing the basic components of a circuit, the video then explains the quantities of current, potential difference, resistance, and resistivity. Electron flow and conventional current flow are discussed before moving to Ohm's law and a discussion of ohmic and non-ohmic behavior in components. Finally, the formulas for electrical power in electric circuits are derived. 0:00 Introduction 0:23 Electric current 2:12 Electric potential difference 3:14 Electric circuits 4:43 Conventional current 5:16 Electric resistance 7:16 Factors affecting resistance 7:53 Ohm’s law 9:34 Electric power 11:00 Summary More IB Physics Videos & Exam Questions can be found at: Revision Village - IB Physics https://www.revisionvillage.com
