Answer:
Ohm's law | physics | Britannica Ohm's law, between current, voltage, and resistance. The amount of steady current through a large number of materials is directly proportional to the potential difference, or voltage, across the materials. ... Ohm's law may be expressed mathematically as V/I = R.
