Why do electrical engineers use complex numbers? Expressing voltage and current as complex numbers makes the mathematics of power networks a whole lot easier, and is an important part of making sure that the lights always stay on.
How complex numbers are used in electricity? The two axis are simply real or imaginary parts of a complex number. You just convert the polar 10A ✓15° into a complex number in rectangular form, then it’s possible to easily add, subtract, etc AC Voltages or Currents by applying the rules of working with complex numbers.
Why are complex numbers used in engineering? Complex numbers are used a great deal in electronics. The main reason for this is they make the whole topic of analyzing and understanding alternating signals much easier. This seems odd at first, as the concept of using a mix of real and ‘imaginary’ numbers to explain things in the real world seem crazy!.
