Step 1
5.C
We have been provided with an appliance contains a copper wire.When the appliance is not in use, the wire has a resistance of about Ro=5900 ohm.
When the appliance is in operation , the wire has an increased resistance R due to heating. If the temperature increases about 150C.
We have to find the operating resistance of the wire=?
Temperature coefficient of copper is 0.0039/0C
