The Electric Current and Cells: Cells in a Series Circuit

The video explains how potential difference works in series circuits. A single cell provides 1.5 volts, and when two cells are connected in series, the potential difference doubles to 3 volts, making the bulb glow brighter. If cells are placed in opposite directions, the potential difference is zero, and the bulb does not glow. Adding more cells in series increases the potential difference further, potentially causing the bulb to blow out. The current remains consistent throughout the series circuit, even with resistors like bulbs.

How does the current behave in a series circuit with resistors?
