Question

There are two metalic wires of the same thickness made from iron and silver.if the length of iron wire is 12cm what should be the length of silver wire which is equal to the resistance of iron wire?
Resistivity of iron =10×10 to power of -8 ohm
Resistivity of silver= 16×10 to the power of -8

Answer 1

Answer:

10×10 to power of -8 ohm
