AC Circuits

Link: Simulation


This applet simulates the voltage variations in an AC series L-R-C circuit.

The user can control the frequency of the source along with the resistance, capacitance and inductance of the components using scrollbars. The display shows the circuit that is in operation and the phasor diagram. The various phases can be identified from the colour coding.

The phases can also be shown in a four channel oscilloscope display. The oscilloscope functions as per normal with control over the vertical scale, the time base and the triggering levels.
