Power factor is the ? of angle Ө in the impedance triangle.
? power in a circuit is the voltage at a certain instant multiplied by the current at that same instant.
Power factor is a numeric ratio applied to the ? power to yield the ? power . apparent / true. Power factor is the ? of angle Ө in the impedance triangle . cosine. READ. The power formula P = E x I Does NOT apply in all cases. The true power in watts consumed by the circuit is consumed by the ? …
Power factor cos ( Φ ) is an important part of an AC circuit that can also be expressed in terms of circuit impedance or circuit power . Power factor is defined as the ratio of real power (P) to apparent power (S) and is generally expressed as either a decimal value for example 0.95 or as a percentage: 95%.
Power factor is the ratio between the real power and the apparent power of a load in an ac circuit. The power triangle of Figure 3(a) shows that the ratio of real power to apparent power is the cosine of the power-factor angle between real power and apparent power .
For the purely resistive circuit the power angle is equal to zero because of the voltage and current will be in phase; hence the power factor is equal to 1 ( Cos0=1 ) because the reactive power equals zero . Here the power triangle would look like a horizontal line because the opposite (reactive power)... ...
