### Shock Value B/Circuit Lab C Question Marathon

Question Marathon for Shock Value B/Circuit Lab C.
-The path of the Administrator is beset on all sides by the inequities of the selfish and the tyranny of evil men.

-Nothing\'s gonna get deleted. We\'re gonna be like three little Fonzies here. And what\'s Fonzie like? Come on, what\'s Fonzie like?
-Cool?
-Correctamundo. And that\'s what we\'re gonna be. We\'re gonna be cool. Now, I\'m gonna count to three, and when I count three, you let go of your mouse, and back away from the keyboard. But when you do it, you do it cool. Ready? One... two... three.

Okay. Let's start out with a SUPER easy basic question.
Let's say that a circuit has one resistor (lightbulb) and one battery.
The battery produces 10V, and the resistor has 2 Ohms.
How many amperes are running through the circuit?

Classic Ohm's Law question!

Edit: Oops! It appears I forgot to create a question; thanks to the below poster for continuing.

Technically, I believe the previous poster was supposed to create another question, but since they didn't, I will do so, with a somewhat more complex question.

The circuit is as follows:
Bt1 has an unknown voltage. Bt1 is wired to R1, which has a resistance of 5Ω. R1 is wired in parallel with R2(4Ω) and R3(4Ω), which are in series with each other.

if the total current through the circuit is 2 ohms, what is the voltage of Bt1?

Wait hold up what?

If you meant 2 amps...

Try this one on for size...

What's the Norton equivalent current for the following circuit?
A 5 volt battery is attached to a 1kohm resistor, which is then attached to a 470ohm resistor, and finally through a 330ohm resistor back to the other terminal of the battery. The point for simplification of the circuit is across the 1 kohm resistor.

Yes, I did. I thought I later edited that, it must not have gone through on account of my terrible internet connection.
Anyways, I'll take a stab at your problem.

EDIT: Made the same mistake i just corrected above. Your question is...
Transform a delta-circuit where Ra = 2Ω, Rb = 3Ω, and Rc = 4Ω into a Y-circuit containing resistors R1, R2, R3.

... I'm fairly certain we're not the only ones in this event... That's the question, if the edit was somehow missed.

I was trying to give someone else a chance, but I guess no one took it

Nice pic.

Soo... Let's see if we can get someone else into this.

3 3 ohm resistors are in parallel and connected to a 5v battery. A fuse is in the battery that is rated for 4A. Will the fuse blow?

### Re: Shock Value B/Circuit Lab C Question Marathon

Wanted to do some logic gates since they sound interesting:

1. What will the output be if A is true and B,C, D are false?
2. What will the output be if A and B are false and C and D are true?
3. What will the output be if A,B,C, and D are all false?

Bonus: write a boolean algebra expression for the output in terms of A, B, C, and D
Not worth your time: make a truth table for this gate system

Disclaimer: I just looked up logic gates for the first time so I'm not sure if these questions are 100% legit.

Ok, I waited since I virtually alternated answering every other question so far, but I'll go ahead.
I'm a programmer, so I can hopefully handle logic...
(although, i will note that i think the rules only cover DC, not digital logic. But it's still good practice anyway.)
These comparisons are what run your computer...
