How many volts would it take to push 1 amp through a resistance of 1 ohm?

.

Explanation:

Ohm's Law give the following relationship between the potential across a conductor, the electrical resistance of that conductor, and the current through that conductor:

.

It is given that the current through this conductor is , and that the electrical resistance of this conductor is .

Note, that the unit of electrical resistance Ohm is a composite unit; (volts per ampere.)

Substitute the value of and into the equation from Ohm's Law to find the potential across this conductor:

.

answer: a. same unit

explanation:

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.
