Solution
Correct Answer:
Voltage across it (at constant temperature)
- 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.
- Mathematical Form: I∝V⟹V=IR, where R is the constant of proportionality called resistance.
- Validity: It applies primarily to ohmic conductors (like metals) within linear regions of operation.
- Conclusion: The current is proportional to the voltage (potential difference).
This easy difficulty physics question is from the chapter current electricity, covering the topic of ohm's law (conceptual). It appeared in the 2025 exam.
