HP13/PHASOR 04b: HP-50g Complex Numbers in Action.
Solving an equation with complex number coefficients. Not in electrical engineering? Don't worry, just get to the equation to solve (KCL1), and take it from there. Using complex numbers to solve an AC circuit, determining the AC currents in different parts of an induction motor and the active and reactive power absorbed from the utility company. The exercise has been set as a numerical exercise. The viewer not interested in electric machines may just accept that the voltage such and such, or current such and such, are represented by corresponding complex numbers and that the expressions are the ones illustrated. The point of the video is to show the flexibility of the HP-50g (and of the HP-49g+, and of the HP-48GX) to work with complex numbers.
