Potential difference
विभवांतर
In this Class 10 Science topic from the Electricity chapter, students learn that potential difference is the work done to move a unit charge between two points in an electric circuit. They explore the relation V = W/Q, understand the volt as its SI unit, and learn how a voltmeter measures it when connected in parallel. The topic also explains why potential difference drives current and how it connects with resistance and Ohm’s law in simple circuits.
