Power in a thermocouple is given by ________(a) Power =E^2 rms / Rheater(b) Power = E^2 rms(c) Power = Rheater(d) Power = E^2 rms × RheaterI got this question in an interview.I'd like to ask this question from True RMS Responding Voltmeter topic in portion Electronic Instruments of Electrical Measurements

Answer»

The CORRECT answer is (a) Power =E^2 rms / Rheater

For explanation I would SAY: The power consumed in a thermocouple is given by the relation

Power =E^2 rms ⁄ Rheater

where, Erms is the r.m.s value of the a.c. INPUT signal

Rheater is the resistance of the HEATER.
