causing an electric current. If the length of the wire of the same material is doubled and the area of cross-section is halved

Sahay Sir > Question Answers > causing an electric current. If the length of the wire of the same material is doubled and the area of cross-section is halved
A conducting wire of length ‘ l l’, area of cross-section A and electric resistivity ρ is connected between the terminals of a battery. A potential difference V is developed between its ends, causing an electric current. If the length of the wire of the same material is doubled and the area of cross-section is halved, the resultant current would be :
