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)
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.
