Increasing positive angles of a phasor move clockwise from the reference point. The more reactive the load, the lower the power factor. The voltage across an inductor leads the current through it by 90degree. The derivative of a sine wave is a cosine wave. For an inductor the voltage Lags the current through it by 90 degrees. A power factor of 1 indicates that maximum power is being delivered. Inductive reactance does not dissipate electrical energy. The heavier the current flow for a given voltage, the larger the value for admittance. Impedance is the combination of capacitive reactance, inductive reactance, and dc resistance. Inductive reactance is plotted on the negative imaginary axis on an impedance diagram.
