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.

Up to 1 questions from this page. Select your focus, then start.
The SI unit of resistance is the ohm (Ω). According to Ohm’s law, \(R=\frac{V}{I}\); a resistance of \(1\,\Omega\) allows a current of \(1\,\text{A}\) when the potential difference is \(1\,\text{V}\). Volt is the unit of potential difference, while ampere is the unit of current. Exam tip: remember the symbol Ω for resistance.
