Answer

already exist in the wire. Explanation 1. Analyze the analogy The analogy compares water in a pipe to electrons in a wire. Water must be supplied to a pipe, but electrons are inherent in the atomic structure of the copper wire. 2. Determine the correct statement Electrons already exist in the wire as part of its atomic structure and do not need to be supplied externally.
