Resistance Definition Physics
The property of a conductor by virtue of which it opposes the flow of electric current through it is called its resistance.
- The measure of a conductor’s opposition to current flow is known as the resistance of the conductor. Different conductors have different resistance to current flow.
- Resistance is denoted by the letter R.
- The resistance, R of a conductor is defined as the ratio of potential difference, V across the conductor to the current, I flowing through it.
