simple counters Counting is a fundamental function of digital circuits. A digital counter consists of a collection of flip-flops that change states (set or reset) in a prescribed sequence

Junction potentials Whenever we change electrolyte or solvent there is a cost in that we create a double layer (electrode)which has a small but often measureable potential We call this potential a junction potential
