Witryna24 maj 2013 · Mathematically power factor is the product of voltage drop across the element and current flowing through it.. Considering first the DC circuits, having only DC voltage sources, the inductors and capacitors behave as short circuits and open circuits respectively in steady-state.. Hence the entire circuit behaves as a resistive circuit … Witryna24 lut 2012 · This is commonly done by a capacitor bank. Let’s explain in detail: we know that active power is expressed = vIcosθ. Where, cosθ is the power factor of the system. Hence, if this power factor has got less valve, the corresponding current (I) increases for same active power P. As the current of the system increases, the Ohmic loss of the ...
