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:

the first american roller coaster was the mauch chunk switchback railway, built in the mountains of pennsylvania in the mid-1800s. the track, originally built to send coal to a railway, was reconfigured as a "scenic tour."
