Question

3. The resistance of a wire of 0.01cm radius is 10 . If the resistivity
of the wire is 50x108 Om , find the length of the wire.​

Answer 1

Answer:

The resistance of a wire of 0.01 cm radius is 10 Ω. If the resistivity of the material of the wire is 50 × 10⁻⁸ ohm meter, find the length of the wire. ⇒ l = 0.628 m. Hence, the length of the wire is 0.628 m
