K7-46. Phasor Disc
To demonstrate "phasor" rotations and phasor addition.
Rotating plastic phasor disc on mount.
This model can be used in adding volatges of different phase in an RLC circuit. Draw the phase relations then rotate the model to represent the applied alternating voltage. It is also useful in adding light from a series of segments of a single slit, simple harmonic motion (single phasor), or the addition of two mechanical waves.
