It is usually a rectangular boundary of a Venn diagram. It is the area surrounding all the circular shapes in these diagrams.
Universal set.

It is the set of "everything".
If the universal set, U, has N elements then it has 2N subsets.
The complement of a set refers to the elements that are not included in that set but are part of a larger universal set. For example, if the universal set is all natural numbers and set A consists of even numbers, the complement of set A would be all the odd numbers within the universal set. Mathematically, the complement of set A is often denoted as A'.
Universal set.
"Universe" and "universal set" are two unrelated concepts.
The universal set is the set of all possible elements under consideration. You can have a universal set of all people, or all bird species, or all numbers or whatever. You can even have a universal set of all people and all bird species and all numbers as one big set.
If the universal set contains N elements then it has 2N subsets.
Yes. A null set is always a subset of any set. Also, any set is a subset of the [relevant] universal set.
The universal set is the set containing each and every element under consideration.

The complement of an empty set is universal set
Ohm's law is not considered a universal law since it specifically applies to electrical circuits that exhibit ohmic behavior. A universal law would apply universally across all physical phenomena. An example to illustrate this is the behavior of certain materials that do not obey Ohm's law, like semiconductors or diodes, which have nonlinear resistance characteristics.
