| Abstract: | Calculates the electric conductivity of the wire by measuring the resistance under certain temperature with two-arm bridge,and then calculates the electric conductivity of the wire based on the law of Wiedemann-Franz.The result shows that measuring the thermal conductivity of metal with electric method is feasible and has high accuracy. |
| Keywords: | Law of Wiedemann-Franz Two-arm bridge Thermal conductivity Metal wires |
