Sup Forums is not for making your homework.
Also 18+, little one.

Okay, I calculated it.
Now what?

chooo choo

Create a low pass filter.

>Create a low pass filter
how to make voltage meter that can measure signals like PWM or other non flat? I was thinking about making an array and pulling out highest results, but might be problem with aliasing or something like that.

It'll be approx 1.5V

I'm sure any further accuracy will be irrelevant

1 V

See how an oscilloscope works

6v

>Drawing the ground
lol

Did it with you unhelpful fags

230v

Is equal to the amount of volts required to get your mom's fat ass to move

Just woke up. Ezpz

>Calculate the voltage

I sincerely hope that your pic is a joke

pretty sure its because its drawn in a circuit simulator, those things don't work without grounding the circuit.

wow, you are so smart, you deserve a special shiny medal

I = 3V/(R1+(R2 || RM))
UR2 = 3V-R1*I
done

No joke, I verified the results with multisim

1.5[V] app.

t.electrical engineer

Your notation is though

>>not using LTSpice

Alright plebs. Calculate resistance between two red dots. Grid extends forever.

cs fag here. What are the best books to learn this stuff?

-1/12

R

For understanding ohms law? I don't think so.

Any high school physics book

correct

wrong

takes 2 minutes to verify with circuitlab

jk, first guy was wrong, second was right

also I was wrong because I read 10M as 1M which is also what the guy who was wrong did

If you say so

Oh really? Good for me. I double checked my math so I hoped it was correct

It's a simple circuit bro no need to bring Kirchoff into this.

V_o = (V_in(R_2 || R_meter)) / (R_1 + (R_2 || R_meter))

I suck at physics, but wouldn't we need to now the actual amperage to be able to reliably calculate the voltage, due to Ohm's law? That's always how we calculated it back in school, I didn't knew it was possible without it.

Also, I'd just use a multimeter.

You have voltage and resistance you can calculate amperage.

kek'd.

no

Entry level EE books.
If you know some basics it's easy enough to get started.

That's high school physics, just do your homework retard

You could have just pararelled and used a voltage divider. Lot simpler.

Nope. You can use voltage division. Or you can use a test current thru each mesh, but that's overkill for such a simple circuit.

How is this physics?

circuit analysis 2nd edition by cunningham/stuller
it's by far the best and only book i have ever used. there is also a solutions manual online that has very detailed steps.

it's R2.

amazon.com/Advanced-Physics-Tom-Duncan/dp/0719553695
one of the most comprehensive books for an introduction to physics you can find.

isnt this year 11 physics? bro its easy shit just get good.

nope.

Do your own fucking homework you stupid cunt.

Well if you read the thread you'd see that I did

I think I've seen something similar...
>10.
Year, there it is.

THE GOOGLES COLORS OF COURSE!

2/Pi * R

Calculate the voltage across your mums fat tits

A little less then 1.5 Volt.

For any practical purpose this is the right answer.

correct!

It's more of a reference point for simulators where every other voltage gets calculated from.

A tiny bit more than 1.5V.

To get the exact voltage, just compute the equivalent of the 470k and 10M resisters in parallel using the "reciprocal of the sum of the reciprocals" method. Once you have that, you can just use the series resistor voltage drop formula V*(a/(a+b)).

I've never had any EE or physics courses, but isn't this like absolute babby-tier?

Underrated post.
