It is the set of "everything".
If the universal set, U, has N elements then it has 2N subsets.
The null set. It is a subset of every set.
Universal set.
"Universe" and "universal set" are two unrelated concepts.
A universal set is a set that contains all the elements under consideration for a particular discussion or problem. It is used in set theory to define the range of possibilities within a given context.
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.
It is the set of "everything".
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.
If the universal set, U, has N elements then it has 2N subsets.
The complement of an empty set is universal set
The null set. It is a subset of every set.
