Technician A says a potentiometer is a voltage divider circuit used to measure movement of a component. Technician B says a magnetoresistive sensor alters current flow through the sense circuit when influenced by the magnetic field.

Who is correct?

The temperature of air decreases as it is compressed by an adiabatic compressor. a)- true b)- false

Ahot wire operates at a temperature of 200°c while the air temperature is 20°c. the hot wire element is a tungsten wire of 5 um diameter and 2 mm in length. plot using excel current, heat transfer and heat generated by the wire for air velocity varying from 1-10 m/s in steps of lm/s? matlab the sensor voltage output, resistance, or assume nu 0.989 re033pr13 take air properties at tr (200°c20°c)/2 = 110°c properties of tungsten: c 0.13 kj/kg. k 3 p 19250 kg/m k (thermal conductivity) = 174 w/m. k
