Keeping the cross-sectional area of a wire the same, if its length is doubled, the resistance will become ______?
کسی تار کے کراس سیکشنل ایریا کو ایک جیسے رکھنا ، اگر اس کی لمبائی دوگنی ہوجاتی ہے تو ، مزاحمت ______ بن جائے گی؟
Answer: Double
Explanation
The resistance of a wire is directly proportional to its length (R ∝ L).
If the length is doubled and the area remains the same, the resistance will also double.
