Question

Q2. A metallic wire has a resistance of 1 ohm per metre. 1) find total resistance of four times the length of wire. 2) what will be the resistance of 2.5 m long wire 3) what will
resistance of 6 m long same material but with four
areat of cross section​

Answer 1

Answer:

Resistance of a metal wire of length 1 m is 26 Ω at 20°C. If the diameter of the wire is 0.3 mm, what will be the resistivity of the metal at that temperature?
