WebPower Set Definition. A power set is defined as the set or group of all subsets for any given set, including the empty set, which is denoted by {}, or, ϕ. A set that has 'n' elements has 2 n subsets in all. For example, let Set A = {1,2,3}, therefore, the total number of elements in the set is 3.
