Ohm’s law
ओम का नियम
In Class 10 Science, the topic Ohm’s law introduces the relationship between potential difference, current, and resistance in an electric circuit. Students learn the formula V = IR, understand how voltage and resistance affect current, interpret the straight-line voltage–current graph for an ohmic conductor, and use the law to calculate unknown electrical quantities. The topic also builds a foundation for analysing simple circuits in the chapter Electricity.
