Question
true or false: The resistance of a copper wire increases, when its diameter is increases.
true or false: The resistance of a copper wire increases, when its diameter is increases.
Homework Answers
Answer #1
Increase in diameter increases the area of cross-section of the
wire. Resistance is inversely proportional to the area of
cross-section of the wire. Hence with the increase in diameter the
resistance will decrease. Hence the statement is false.
