Question

A copper coil has a resistance of 200 ohms at 0 degC. Calculate its resistance at 80 degC. (temperature coefficient of copper = 0.004041 degC-1)
Options
A 264.65 ohms
Correct Answer
B 264.65 k-ohms
C 286.65 ohms
D 286.65 k-ohms
Correct Answer

Option A is the correct answer.

Detailed Explanation

R=R0(1+alpha dT)=200(1+0.32328)=264.66 ohms.

Hint

R=R0(1+alpha dT)=200(1+0.32328)=264.66 ohms.
