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.
The aim is to provide MCQs on Laws of Resistance objective questions and answers to understand the concepts of Resistor and it’s types. If you are willing to learn the concepts of Basic Electronics MCQs multiple choice questions with answer then read all the questions and answers. You will be surely able to qualify for all kinds of Quiz / tests / Interviews after understanding the Introduction to Laws of Resistance. If you are a students, technician or teacher then you can learn the basic concept of Laws of Resistance applications, principle and function.
