According to Ohm's law, how many volts are required to push one ampere through one ohm of resistance?

Ohm's law states that the voltage (V) across a conductor is directly proportional to the current (I) flowing through it and the resistance (R) of that conductor. This relationship is expressed mathematically as V = I × R.

When applying this law to the scenario given, if you have one ampere of current flowing through one ohm of resistance, you can substitute the values into the formula:

V = 1 ampere × 1 ohm = 1 volt.

Thus, only one volt is required to push one ampere through one ohm of resistance, which aligns perfectly with the fundamental principles of electrical circuits described by Ohm's law. Understanding this basic concept is crucial for anyone in the electrical field, as it is foundational to analyzing and designing electrical systems.
