What is meant by implied powers, give an example?

Implied powers are political powers of U. S. government which have not been explicitly granted by the Constitution but that are implied because are necessary to carry out the powers that are expressly listed in Constitution. They are the secondary power that the government has because of the existences of the primary powers. These implied powers are necessary for the function of any given governing body.

The bank case's existence is an example of implied powers. The Constitution doesn't give to the Congress the right to establish a bank, but its defenders said that it was necessary to carry out the Congress' power to collect taxes.
