Filter & Transfer Function

Z 1. V out. V in. Z 2. Filter & Transfer Function. To determine filter type, look how H V as a function of frequency. Z 1 and Z 2 could include multiple components. RLC at Resonance. At resonance: current is max. Z eq =R current and voltage are in phase.

Exam II Review: AC Power

Exam II Review: AC Power. Average power. rms value. The average ac power ( P av ) is the power dissipated on the load resistor. 0 ? cos q ?1, dependent on the complex load. ideal power factor: cos q =1, Z=R, pure resistive load. Review cont.: Complex Power.

Power factor correction

Power factor correction. It is very common that load (motors, power lines, etc) is inductive, i.e. Q>0. Common practice to bring the power factor to unity is to connect a parallel capacitor across the load, such that Q C =-Q. (the method is easy and need not break the circuit).
