Tom accidentally broke off a capacitor on his motherboard.

Peter didn't even know what a capacitor does.

Maybe I just need a bigger capacitor.

By placing the 0.02μF capacitor on top of the whistle chip, the circuit oscillates at a lower frequency. […] It is possible to pick resistors and capacitors that will make the pitch higher than humans can hear.
