Figure 3 shows that the same thing happens with a purely inductive load. Precision: decimal places. At the end of this text, you can also find information about the properties of complex numbers (most of which are based on the conjugate or the absolute value of complex numbers) and even some practical applications of them. The quantity cos is the Power Factor (PF) and varies from one for a perfectly resistive load, to zero for a perfectly reactive load. Regular Equations Step by Step; Inequalities Step by Step; . The imaginary part is implemented in the Wolfram Language as Im [ z ]. You must use * to indicate multiplication between variables and coefficients. Lets take a look at how complex numbers are multiplied together by simplify complex numbers calculator. As you would expect, the sinusoidal voltage across the resistor (green trace) results in a sinusoidal current with the same phase (blue trace). This is the Apparent Power (S) and is given by S = |V||I|, measured in Volt-Amps (VA). The real part is 2 and the imaginary part is 3, so the complex coordinate is (2, 3) where 2 is on the real (or horizontal) axis and 3 is on the imaginary (or vertical) axis. Complex numbers can also be entered in the polar form r∠ , where r is the signed module (or length) and is the argument (or angle) of the complex number.
