Question

a silver wire has a resistance of 2.1 ohm at 27.5 degree Celsius and a resistance of 2.7 ohm at hundred degree Celsius determine the temperature coefficient of resistivity of silver​

Answer 1

Answer:

A silver wire has a resistance of 2.1 Ω at 27.5 °C, and a resistance of 2.7 Ω at 100 °C. Determine the temperature coefficient of resistivity of silver.

Answer

Temperature, T1 = 27.5°C

Resistance of the silver wire at T1, R1 = 2.1 Ω

Temperature, T2 = 100°C

Resistance of the silver wire at T2, R2 = 2.7 Ω

Temperature coefficient of silver = α

It is related with temperature and resistance as

Therefore, the temperature coefficient of silver is 0.0039°C - 1.
