## Laws of Resistance – Definition

**Resistance** is basically an ability of an electronic component “**Resistor**“. According to the laws of resistance, it depends on length, cross-sectional area, nature of material and temperature. You can do a calculation with the formula **R = ∝ L/A. Rho **is a constant factor which is called **Resistivity. **All the **Laws of Resistance MCQs with Answers** are published according to the new study syllabus for academic year **2021-22.**
