Stuffed Stuff Quiz - Spoiler Alert

The major use for tantalum, as the metal powder, is in the production of electronic components, mainly capacitors and some high-power resistors[35]. Tantalum electrolytic capacitors exploit the tendency of tantalum to form a protective oxide surface layer, using tantalum powder, pressed into a pellet shape, as one "plate" of the capacitor, the oxide as the dielectric, and an electrolytic solution or conductive solid as the other "plate". Because the dielectric layer can be very thin (thinner than the similar layer in, for instance, an aluminium electrolytic capacitor), a high capacitance can be achieved in a small volume. Because of the size and weight advantages, tantalum capacitors are attractive for portable telephones, personal computers, and automotive electronics.

The first question has more than one possible answer - any electronic device that has capacitors is likely to have tantalum in it.

Stuff's Daily Quiz is stuffed. I still only got 7/15.

I wondered about that too. This brings my score to 6!
