Electrical resistance: meaning, definitions and examples
⚡️
electrical resistance
[ ɪˈlɛktrɪkəl rɪˈzɪstəns ]
physics
The opposition to the flow of an electric current through a conductor. It is measured in ohms and can be affected by the material, length, and cross-sectional area of the conductor.
Examples of usage
- The electrical resistance of a wire increases with its length.
- A higher cross-sectional area of a conductor will result in lower electrical resistance.
general
The ability of a material to resist the flow of electricity.
Examples of usage
- Copper has low electrical resistance, making it a good conductor of electricity.
- Rubber has high electrical resistance, making it a good insulator.

Etymology
The concept of electrical resistance dates back to the 19th century when scientists were investigating the properties of electricity. It was through experiments and observations that the relationship between current flow and resistance was established. The discovery of Ohm's Law by Georg Simon Ohm in 1827 played a crucial role in understanding the behavior of electrical resistance in circuits. Since then, electrical resistance has been a fundamental concept in the field of electrical engineering and continues to be studied and applied in various technological developments.
