Let G ( s) s 4 3s 2 10s 2 s( s 2)( s 3) Compute the partial fraction expansion of G(s). 3. The (average) RMS voltage and current for an air‐conditioner for a home in South Florida is 115 volts and 12 amps. Further, the phase difference between voltage and current is 10 degrees with current lagging the voltage. Represent the voltage and current as complex exponential time functions. Use the complex conjugate concept to calculate the energy consumption per hour of operation. Also, calculate the reactive power of this AC unit. Assuming electricity costs $0.12 per kWh, what is the utility bill for the month of July? ...
