The Value Of Fluorspar The U.S. Department of the Interior lists fluorspar as one of 50 Critical Minerals and metals vital to our country. As is the case with many critical minerals mined overseas, America's reliance on foreign sources of fluorspar poses a threat to both our economy and our national security. Fluorspar is an
JK flip-flop is a commonly used type of flip-flop and is used in different applications as universal flip-flop circuitry. Its function is like the RS flip flop having the same SET and REST inputs. The difference is that JK flip flop not supported the invalid states of RS Latch. Its name JK flop is given due to its creator Jack Kilby.
