Total circuit current in the time domain; Determine the voltage in the inductor in the time domain; The total active and reactive power; Does this system operate on low power factor? If so, explain what the consequences are for the circuit and what can be done for its correction. Also add the calculations if you need to raise the new FP to the established value.

At steady state, air at 200 kpa, 325 k, and mass flow rate of 0.5 kg/s enters an insulated duct having differing inlet and exit cross-sectional areas. the inlet cross-sectional area is 6 cm2. at the duct exit, the pressure of the air is 100 kpa and the velocity is 250 m/s. neglecting potential energy effects and modeling air as an 1.008 kj/kg k, determine ideal gas with constant cp = (a) the velocity of the air at the inlet, in m/s. (b) the temperature of the air at the exit, in k. (c) the exit cross-sectional area, in cm2
