A metallic wier has a resistance of `120 Omega at 20^@C.` Find the temperature at which the resistance of same metallic wire rises ot `240 Omega` where the teperature coefficient of the wire is `2xx10^(-4) C^(-1).`

Text Solution

AI Generated Solution

To find the temperature at which the resistance of the metallic wire rises to 240 ohms, we can use the formula that relates resistance and temperature. The formula is given by: \[ R = R_0 (1 + \alpha (T - T_0)) \] Where: - \( R \) is the resistance at temperature \( T \) ...
