Balanced Three phase AC circuit Delta connected

A balanced three phase AC circuit systems is energized by three equal alternating emf's of the same frequency but 120 degree apart. The phase impedance are equal. Also the currents are equal and 120 degree apart. Three AC emf's differing in time phase by 120 degree DELTA (MESH) CONNECTED SYSTEM This...

Power Factor for a more efficient circuit and loading

Power factor is an important aspect to consider in AC circuit, because any factor less than 1 means that the circuit wiring has to carry more current than what would be necessary with zero reactance in the circuit to deliver the same true power to the resistive load.     When expressed as fraction, the ratio between true power and  apparent power is called the power factor of the...
