ohm's law (conceptual)

Question

Ohm's law states current through a conductor is directly proportional to?

RankGuru · Accepted Answer

1. **Statement**: Ohm's law states that for a metallic conductor, the current ($I$) flowing through it is directly proportional to the potential difference ($V$) applied across its ends, provided temperature and other physical conditions remain constant.
2. **Mathematical Form**: $I \propto V \implies V = IR$, where $R$ is the constant of proportionality called resistance.
3. **Validity**: It applies primarily to ohmic conductors (like metals) within linear regions of operation.
4. **Conclusion**: The current is proportional to the **voltage (potential difference)**.
