##### RLC Networks

RC charge and decay: This demo helps students visualize the time dependent behaviors exhibited by a capacitor with an AC input. It shows that when charging a capacitor, in series with a resistor, the capacitor voltage will depend on the time constant $\tau=RC$

RL circuit: Show students how a resistor and inductor react to square wave inputs.

RLC resonance: Utilizes a series bandpass and series bandstop filter to demonstrate the resonance that occurs when combining a resistor, capacitor, and inductor.

Low-pass and high-pass filters: This demo shows the frequency dependence of RC circuits in various configurations.

##### Diodes

Quantum mechanics of diodes: Uses several arrangements of LEDs to show the useful properties of the diode.

##### High Voltage

Jacob’s Ladder: Electric arcs continuously rise between two vertical conducting bars held at a large voltage (15kV).

Tesla Coil: Generates 1.2 MV of high frequency to generate long arcs of electricity through the air.

Mini Tesla Coil: Desktop versions of the spark gap Tesla coil which produces inch long sparks and can light bulbs in close proximity.
