Electric Circuits - Series and Parallel Circuits [IB Physics SL/HL]

This video provides an in-depth explanation of series and parallel circuits, detailing how current and potential difference behave in each configuration. It introduces the junction rule, which is based on the conservation of charge, and the loop rule, derived from the conservation of energy, to analyze circuit behavior. The video further explains how to calculate equivalent resistance for resistors connected in series and parallel, demonstrating that series connections increase total resistance while parallel connections decrease it, consequently affecting the overall current in the circuit.
