Resistor tree – EveryCircuit
Play with the resistor values and the voltage applied, and see the difference on the graph and on the currents and voltages throughout the resistor tree. If you can’t figure out how to run or how to change values, ask for a demo – send Nathalia an email.

RLC source free. – EveryCircuit
Source free, second order series circuit. Click on the switch to toggle between one state (charging the capacitor) to the other state (discharging it through the series circuit composed of the 1mH and the 1Ohm resistor). Try changing the resistor to see the transient behavior of the voltage on the capacitor (in orange) and the current through the circuit (in blue). Click on the top left side of the screen to toggle between graph showing and hidden.
