Question

What is meant by resistance of a conductor? Name and define its SI unit. List the factors on Which the resistance of a wire affected, Derive the formula for series combination of three resistors R1,R2 &R3​

Answer 1

Explanation:

Resistance is the property of the conductor to resist the flow of current. SI unit of Resistance is Ohm. The resistance of current depends on Material of the wire, length and cross-section area of the wire and temperature. ... length :- resistance of a conductor is directly proportional to its length.
