Resistance
प्रतिरोध
In Class 10 Science, the topic Resistance introduces how a conductor opposes the flow of electric current in the chapter Electricity. Students learn Ohm’s law and the relationship between voltage, current, and resistance, expressed as V = IR. They explore how resistance depends on a material’s length, cross-sectional area, and temperature, and apply these ideas to understand resistors, circuit calculations, and the effects of connecting resistors in series and parallel.
