Suppose the RTD of given Problem has a dissipation constant of and is used in a circuit that puts 8 mA through the sensor. If the RTD is placed in a bath at 100°C, what resistance will the RTD have? What then is the indicated temperature?
Problem An RTD has
α (20°C) = 0.004 /°C.
If R = 106 Ω at 20 °C,
find the resistance at 25°F?
An amplifier has an input resistance of 1 k Ω, an output resistance of 200Ω, and a short-circuit trans-conductance gain of 0.5 S. Determine the open-circuit voltage gain, the short-circuit current gain, and the open-circuit trans-resistance gain.
