1. The problem statement, all variables and given/known data The problem and its solution are attached. 2. Relevant equations N/A 3. The attempt at a solution All I think I know is that pins 7 and 14 are used for powering the integrated circuit because that's what I believe I read but, I don't fully understand what's going on. I believe the pins that get power are those connected to little ground symbols For example, is it possible for pins 4, 5 and 6 to also take in power? Most importantly, I don't understand why “the 7432 [integrated circuit] performs as a 2-input OR gate when wired as shown in [the figure attached to this forum post]”. Could someone please elaborate about all this for me? Any help in getting me to fully understand this problem would be greatly appreciated!
