LCR paradox

5L20.21 • D+5+1

diagram for demo

RLC Paradox. A signal generator drives a LC circuit at resonance. 3 lightbulbs are placed to qualitatively demonstrate the amount of current through the capacitor, inductor and signal generator. Lamps 1 and 2 glow brightly, but lamp 3 stays dark. Removing the lamps individually gives an idea to the current distribution. A current/voltage probe can also be provided for this demo.
