Question

define parallel connection

Answer 1

 two simplest of these are called series and parallel and occur frequently. Components connected in series are connected along a single path, so the same current flows through all of the components. Components connected in parallel are connected along multiple paths, so the same voltage is applied to each component

Answer 2

A parallel circuit is two or more elements with each terminal connected to the corresponding terminal of the next device so that the same VOLTAGE appears across each element.
