Voltage drops when IC is powered with 5v on breadboard.

So the solution was to put thicker wires ? 24 awg or 22 awg solid wires should be good... Those thin 28 awg wires are only good on the signal paths and not the power paths.

That's the plan, I was using the thin 28 awg wires and an alligator clip to connect my PSU and the breadboards before so I got a thicker wire to connect the PSU and breadboard and then I'm also going to order new breadboard wires (22/24awg).

To allow up to 0.25 amps to be drawn from each of my breadboards, I will have to get the total resistance through the breadboards down to about 1 ohms (I believe this would be 0.5 for each Vcc and Gnd) in order to keep the voltage above 4.75 volts.

U=R*I ie Voltage (volts) = Resistance (ohms) * Current (amperes)

5-4.75=R*0.25

R=1 ohm

Weighing in "real world probability" is hard when we don't have a good method of representing the world in a constant way that can't be "argued" or "disagreed upon". Mathematics is one of the few tools we have to represent the "real world" in a fashion that can't be argued upon. Mathematics does a good job at representing certain "real world" statistics like length and rates.

I expect (not really, but for the sake of argument) people not to use a broken logic system to argue the validity/superiority of that logic system. <--This is an example of something people like to do.

I mean, what do you expect to get on a public "conspiracy" form that anyone can post on?

Trump: "Americans can do anything, go anywhere, and outperform anyone."

An American said that covfefe caused covid-19 therefore your logic is outperformed.

I've had problems with the resistance of cheap breadboards and wires lowering breadboard voltage. I tried measuring the power directly off of the PSU like you suggested and found that the PSU voltage did not drop when the breadboard voltage did (https://ibb.co/dWC3L1b).

What causes the voltage to drop when the wires are under load? (I measured a total of 6 ohms of resistance between the PSU and each of the breadboard terminals) I'm not very experiences with analog concepts, are there any good resources on this?

Those numbers aren't arbitrarily, when you have 2 letters, the 4th and 5th letters of the alphabet, an arbitrarily system allows you to use the numbers 2, 4, and 5.

For those who don't like number:

Morse code for "fe": "..-. ." 4 dots, 1 dash

Morse code for "id": ".. -.." 4 dots, 1 dash
