Re: [Phys-L] LC circuit simulation

This effect has real engineering consequences in the required minimization 
of radiation from power supply circuitry:

> From Am. J. Phys., Vol. 72, No. 5, May 2004 ==>

"For a switched-mode power supply, energy transfers between capacitors
and inductors are an integral part of its operation. To comply with EMC
regulations, it seems that the power supply engineer must compromise
between power lost through adding an external resistor R vs radiation. In
cases, where this loss is unacceptable, shielding remains the only option."

Dissipation is mandated, and nature will find a way - she has invented
RADIATION!

only if it have a resistance. If you only have a L and a C. it "must"
continue oscilating forever

after 3 hours, phet circuit construction kits loses around 5%.
