How do short circuits occur class 7

WebA short-circuit takes place when a part of a wire carrying current touches the other wire and gives the electricity a path of less resistance. Briefly, a short circuit gives the electricity path of least resistance between two points, which means the short circuit will produce more heat and lead to burns and fires. 10 WebNov 11, 2024 · That current cycles through a closed circuit, which is a loop.
