Did you know?
WebTemperature dependence of resistivity. A resistance thermometer uses a copper wire as the temperature sensor. The resistance of the wire is 50.0\ \Omega 50.0 Ω at ice-point and 69.0\ \Omega 69.0 Ω at steam-point. What is the temperature measured by the thermometer if the resistance is measured at 55.0\ \Omega 55.0 Ω? WebThis degree of resistance to electricity is defined by another property of the material called Resistivity. ... To use the above formula, L and A must be in compatible units. The …
The electrical resistivity of most materials changes with temperature. If the temperature T does not vary too much, a linear approximation is typically used: where is called the temperature coefficient of resistivity, is a fixed reference temperature (usually room temperature), and is the resistivity at temperature . The parameter is an empirical parameter fitted from measurement data, equal to 1/ .
