Two resistors are combined in a circuit. First, they are combined in series. Then, they are combined in parallel. What is the equivalent single resistance of each setup?

Yup.

EDIT: And did you notice that exactly three people have posted on this chat?

Who came up with the idea of "animal electricity" and what was its historical significance?

Luigi Aloisio Galvani? He is recognized as having pioneered bioelectromagnetics, one of the first in the field of bioelectricity.Is that enough?

Yep, your turn! (Sorry, I meant its historical significance... his historial significance is a little outside the scope of the rules)

Sorry to interject, but do you guys think that real tests will be as trivia/fact based as this QM seems to be going in the trend of?
I would have thought it would be much more calculation based.

So far, this has just been going over concepts. I'd expect lots of basic calculations in the beginning of actual tests (mostly because making up numbers is effort).

Well i mean, its always good to know those random facts because they might appear on a test. and sometimes you rlly cant study for these random facts.

They're not really random so far though
What is a magnetic quadrupole?
A configuration of magnets with four poles (which is useful because the magnetic field decreases faster than that of a dipole)

Sounds good.

Not only is it effort, but you've also gotta run 'em yourself; both for the answer, and to make sure they're realistic enough for to be mathematically plausible.

Answer
Fuses are basically an electrical component used to prevent overcurrent in a circuit. It is usually a metal strip that melts when the current becomes too large therefore breaking the circuit. They are used in electrical appliances, and on the power grid and in our houses.

What is the difference of total resistance of a circuit with 3 resistors of 6 ohms each arranged in a series vs parallel?
