CBSE Class 10 Science 2019 · Paper 31/4/3 · Question 1
Mention the condition under which a current can flow in a conductor.
Answer
A potential difference must be maintained between the two ends of the conductor.
There must be a potential difference between the two ends of the conductor. A current flows through a conductor only when a potential difference is maintained across its ends, for example by connecting it across the terminals of a cell so that it forms part of a closed circuit.
