UNIT THREE ASSIGNMENT
1. An a. c. bridge is arranged as follows: The arms AB and BC consist of non-inductive
resistance of 100 S2, the arms BE and CD of non-inductive variable resistances, the arm
EC of a capacitor of 1 uF capacitance, the arm DA of an inductive resistance. The a. c.
source is connected to A and C and the telephone receiver to E and D. A balance is
obtained when the resistances of the arms CD and BE are 50 12 and 2500 12 respectively.
Calculate the resistance and the inductance of the arm DA. What would be the effect of
harmonics in the waveform of the alternating current source?

Avolume of 2.65 m3 of air in a rigid, insulated container fitted with a paddle wheel is initially at 264 k, 5.6 bar. the air receives 432 kj by work from the paddle wheel. assuming the ideal gas model with cv = 0.71 kj/kg • k, determine for the air the amount of entropy produced, in kj/k
