Define resistance and its unit. What is the cause of resistance? On what factors does the resistance of a metallic conductor depend?
Definition of Resistance Resistance (RRR) is the opposition offered by a material to the flow of electric current. It determines how much a conductor resists the movement of free electrons when a voltage is applied. Mathematically, resistance is given by Ohm’s Law: R=V/I where: R = Resistance (Ohms, Ω) V = Voltage (Volts, V) I = … Read more
