This Electronics Curves Quiz will probably prove to be a little more of a challenge than some of the ones previously appearing in Popular Electronics magazine. Being a rocket scientist won't help you much here, but being a seasoned electronics technician, hobbyist, or engineer will sure come in handy. Be careful to note the axis unit labels - I got tripped up by that from being lazy and missed one. Surely you won't be hindered by such an oversight.

Electronic Curves Quiz

The operation of electronic devices and circuits is often represented by characteristic curves. See if you can match the electronic devices and circuits at left (1 - 10) with their corresponding curves (A - J).

See answers below.

Quizzes from vintage electronics magazines such as Popular Electronics, Electronics-World, QST, and Radio News were published over the years - some really simple and others not so simple. Robert P. Balin created most of the quizzes for Popular Electronics. This is a listing of all I have posted thus far.
