An electric circuit is best described as which of the following?
AAny conducting material kept near a battery
BA closed and continuous path through which electric current can flow
CA wire connected to only one terminal of a cell
DA source of potential difference only
Answer & Solution
Correct answer: B. A closed and continuous path through which electric current can flow
An electric circuit is a closed and continuous conducting path connecting the terminals of a source, allowing current to flow. If the path is broken, current does not flow.
