Question

The resistance of the wire is 3ohm. The length of the wire is 100cm. Then the emf of the cell C is. Circuit diagram is attached
​

Answer 1

Answer:

In our wire resistance calculator, we have listed some materials, which you can select to find their resistivity and conductivity at 20°C. For example, the electrical conductivity of copper is σ ≈ 5.95 * 10^7 S / m and the electrical resistivity of copper is ρ ≈ 1.68 * 10^(-8) Ω * m .
