a length of a wire 2m and its area of cross section is 2ms if the resistivity of the wire is 4×10^-8 ohms meter find the resistance of the wire what will happen to the new resistance of the wire if the new length is made double to the original length |

Answer» Resistance be INCREASED. Step-by-step EXPLANATION: Ro is l/a Because. Length is directly proportional to resistance If lenght increase than resistance will increase |
