What Is Resistance And It SI Unit And Formula? Definition of Resistance Electrical resistance is a measure of opposition to the flow of electric current. … The SI unit of resistance is the ohm (Ω) where 1 Ω = kg⋅m2⋅s− 3⋅A− 2. What is resistance and write its formula? Parameters Resistance Resistivity Formula R =

At what temperature will the resistance of a copper wire becomes three times its value at 0 C temperature coefficient of resistance
What Factors Affect Resistivity? What factors affect resistivity? The resistivity of the materials depends on a few factors, which are temperature, mechanical stressing, age hardening, and alloying. What are the 4 factors that affect resistance? The type of material of which the resistor is made. The length of the resistor. The thickness of the resistor.
