A tungsten coil has a resistance `16 Omega` at
`20^@C`. If the temperature coefficient of resistance of tungsten is `0.004^@C^(-1)`, calculate the resistance of the coil at `80^@C`.
Text Solution
AI Generated Solution
To calculate the resistance of the tungsten coil at \(80^\circ C\), we can use the formula for resistance change with temperature, which is given by:
\[
R_t = R_0 (1 + \alpha (t - t_0))
\]
where:
- \(R_t\) is the resistance at temperature \(t\),
