What is the voltage drop (V1) across the 10 ohm resistor?
Can I use Voltage division to get V1?
Like V1 = (20 x 10)/(10+4)
But when I use nodal analysis and mesh analysis I get different answer (12.30V).
Which one should I use?
Or have I understood the voltage division method incorrectly?
I get 1.75A through the 4 ohm resistor, of which 1.3A (obviously) goes through the 10 ohm resistor and 0.45A (because the voltage drop is only 3V) through the pair of parallel resistors
oh I see what I did wrong, I miscalculated the parallel resistance
it would be 13V if you replaced the 5 ohm resistor with a 20 ohm resistor
@Razetime Usually the user who made the nomination post does it (and relying on DLosc to do it is what caused the first version to die), so I‘d say it’s game for anyone to post it as the user‘s deleted
CMC sort of: Given a number, return its prime factors...most of the time. Your score is length / accuracy, where accuracy is the percentage (from 0.00 to 1.00) of integers > 1 that the program/function correctly factors.
@RedwolfPrograms How can you calculate the %? There's an infinite number of integers, and you either handle all of them or a finite subset, so your accuracy is either 1 (all of them), or 0 (a finite subset)
I guess there would need to be some upper limit for it to make sense, like 2^32-1, since otherwise it's almost always going to be either ×1 or ×(arbitrarily close to 0)
Oh, I was thinking of a subset of integers > 2, if there was a max that had to be handled it'd be different. (I wonder what percentage of numbers < 2^32-1 have only 2, 3, 5, and 7 as factors?)
Compatible programs
When studying numerology, you can say two strings are compatible if they produce the same number under the following operation:
Remove all non-letter characters (i.e. all characters not in ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz)
Map each letter to a number acco...

I wish I hadn't nominated Plumber for LotM. I'd now rather have nominated dotcomma, but I don't want to nominate two language that are both mine and are relatively unknown.
