A complex number is a number that comprises a real number part and an imaginary number part. Definitions and Formulas. You can check how we can do it in practice with the voltage divider calculator. This time, the real part can be written as Re(A * B) = x * m y * n, and the imaginary part as Im(A * B) = x * n + y * m. Remember that complex number calculators use a negative sign in the real part because, at some point, we are faced with the product of two numbers i * i, which by definition is -1. The lengths of the real and imaginary projections are related to the magnitude of the vector cosine and sine of the phase angle respectively. In this case the current lags the voltage by 90, but the average power is also zero. Scan; Clarify mathematic equations; Deal with math question; Top Experts; Improve . How to use the complex roots calculator? Fortunately, we don't have to worry about them here. When performing simple operations on complex numbers, it is helpful to think of them as vectors. We can't measure the real part or imaginary parts in isolation, because that would miss the big picture.
