Question

Full adder adds

• A. 2 bits
• B. 1 bit
• C. 3 bits
• D. 1/2 bit

Hint:

In full adder circuits, remember that two bits are added, along with the carry input, and it outputs the sum and carry.

Answer 1

The Correct Option is A

Step 1: A full adder is a digital circuit that adds three bits (two significant bits and a carry-in).


Step 2: The output of the full adder is the sum and carry-out, so it adds 2 bits along with the carry-in.
