resistance is equal to the potential difference divided by what? give the name, not the unit of measurement.

Resistance equals potential difference divided by electric current.
This comes straight from Ohm's law, the cornerstone of basic circuit theory.

Ohm's Law Explained

Ohm's law states V=I×RV=I\times RV=I×R, where VVV is potential difference (voltage), III is current, and RRR is resistance. Rearranging gives R=VIR=\frac{V}{I}R=IV​, so resistance is potential difference divided by current —no units like amps or ohms, just the name.

Discovered by Georg Ohm in 1827, this holds for ohmic conductors at constant temperature, linking these three fundamentals reliably.

Quick Real-World Example

Picture a 12V battery powering a 4Ω resistor: current flows at 3A since I=VRI=\frac{V}{R}I=RV​. Flip it—divide voltage by that current, and you recover the 4Ω resistance every time.

This powers everything from phone chargers to home wiring, making it a daily hero in electronics.

Common Mix-Ups to Avoid

  • Don't say "voltage" : That's the numerator, not the denominator.
  • Skip units : Question wants "current," not "amperes."
  • Ohmic only : Applies to linear resistors; diodes or bulbs deviate.

TL;DR at Bottom

Resistance = current (the divider in R=VIR=\frac{V}{I}R=IV​). Information gathered from public forums or data available on the internet and portrayed here.
