The circuit in digital exp 06 part 02a could be modified to create a 12-bit adder by adding four more full adders to the circuit. The additional parts the circuit would require would be four more AND gates, four more XOR gates, and four more OR gates.
What is circuit?
An electric circuit is a path along which electrons flow from a voltage or current source, through an external load, and back to the source. The point where those electrons enter the circuit is called the "source" of electrons. The point where the electrons leave the circuit is called the "return" or "ground." In between the source and return are devices called "components" or "elements" that use the electrons to do work.
