What is meant by electric resistance of a conductor? A wire of length l resistance R is streched so that its length is doubled and area of cross section is half. How will the resistance and resistivity change

Answer»

Explanation:

Resistance is defined as the property of a conductor to RESIST the FLOW of CHARGES through it. The resistance of conductor is numerically given as the ratio of potential difference ACROSS its LENGTH to the current flowing through it.
