Concept explainers

Resistivity

Resistivity is a characteristic property of the conductor’s material that measures the extent to which the material opposes the flow of current. It is denoted by the Greek letter “rho”. Electrical resistivity, also known as specific resistance, depends on the nature of the material of the conductor and is unaffected by its dimensions.

Question

The resistance of a resistor at 8 degrees Celsius is given as 47 ohms. Determine the resistance, in ohms, of the said resistor at 25 degree
Celsius. The temperature coefficient at 0 degrees Celsius is 0.00887 per Celsius degree.
