RJM's Demo of The Circular Function Sin as relating to Systems
As shown in Sin And Circle one complete cycle of a sinusoid can be modelled as going round a circle Also Sin AndRC shows if a sinusoid is input to a system, its output is a sinusoid of the same frequency The output amplitude and the phase between input and output are found by modelling the system by a complex number and using its modulus and phase This page allows you to use sliders to change the amplitude, phase and frequency of the sinusoidal current into a system, and when you stop moving a slider, the input current and output voltage sinusoids are drawn both as plots versus time, and moving round the circle.
Just show current I   Show V across Resistor   Show V across Capacitor   Show V across series R + C   Show V across parallel R + C
Set Defaults  Redraw Signals		Resistance R =   Capacitance C =
