Question

At 30°C, the resistance of a conductor is 5 ohm. Find
the temperature at which the resistance becomes
5.2ohm.​

Answer 1

temperature at 5.2 ohm is 70°C.

Answer 2

Answer:

temperature of 5.2 Ω is 70°

Explanation:

Given that :-

   R = resistance of temp T = 30c

   α= temp of coefficient at resistance = 5

    R = resistance of temp= T= ?

  α=   temp of coefficient at resistance = 5.2

Here,

5 = R (1+30α)......(1)

5.2 = R (1+α)......(2)

temperature of 5.2 Ω is 70°
