As an electrician on the job, you encounter an installation that is supposed to have ten 250-watt lamps on a 20 amp circuit. The voltage is 120 volts to each lamp. Is this circuit adequate considering that the load is continuous and the
circuit can only be loaded to 80% of its rating? (You will see the calculation once you submit)
a Yes
b. No

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
