Question

A copper wire of length 2 m and area
croes section 1.7×10-6 m
? has a resistance
of
2 x 10-2 ohms calculate the resistuity
of copper
Ans:-​

Answer 1

Answer:

A copper wire of length 2m and area of cross-section 1.7×10-6m2 has a resistance of 2×10-2ohms. Calculate the resistivity of copper. Thus, the resistivity of copper is 1.7×10-8 ohm-metre
