This video tutorial explains the concept of equivalent resistance in series and parallel circuits. In series circuits, resistance increases with each added resistor due to a single path for charge flow. In parallel circuits, resistance decreases as more resistors are added, thanks to multiple paths for charge flow. The video uses a traffic analogy with toll booths to clarify these concepts, illustrating how series circuits resemble a single path with multiple tolls, while parallel circuits offer multiple paths, reducing overall resistance.
