Question
Ash is working in the lab, and comes across a box of
unlabeled resistors (thanks to his messy coworker who
never puts them back properly).
He remembers that he can find out the resistance using an
ammeter to measure current, and a battery with a known
voltage.

In ohms, what is the resistance of the unknown resistor?
Answer:
Ω.
