In words, what relationship does Ohm's law describe between current and voltage?
ACurrent is inversely proportional to the voltage applied across a path
BCurrent is proportional to the square of the voltage applied
CCurrent is proportional to the voltage applied across a circuit or path
DCurrent is unrelated to voltage and depends only on resistance
Answer & Solution
Correct answer: C. Current is proportional to the voltage applied across a circuit or path
1. Ohm's law in equation form is written as V = IR, with R the constant of proportionality.
2. Rearranged, this states that current I is directly proportional to voltage V.
3. An inverse or squared relationship would not reduce to the simple V = IR form given.
4. So the verbal statement of proportionality between current and voltage is the correct one.
