Electric Circuits - Worked Examples [IB Physics SL/HL]

This video explains how to solve example questions involving series and parallel circuits by applying principles of current and potential difference. It demonstrates calculating current and potential difference in a series circuit with three resistors and then analyzes a more complex circuit with both series and parallel components, showing how ammeter and voltmeter readings change when a switch is closed. The explanation covers calculating equivalent resistance for both series and parallel configurations, applying Ohm's Law, and utilizing the loop rule to determine current and potential differences in different parts of the circuit.
