How do you find the total current (IT) of a parallel circuit?
Pic related
there's a simple equation...
l=mgt4u

V=IR

COME
ON
SON.

What you need is RT.
1/(1/R1+1/R2+1/R3), then Ohm Law.
This is boring, why couldn't you ask something more interesting like individual I in each resistance at least? Are you in middle school? Is this bait?
>>55215825
google node voltage and mesh current
>>55215825
current through what
>>55216073
Or you could just apply ohm's law to each resistor and add the currents
>>55215825
>labels for 8 nodes
>only 2 nodes exist including ground
So this is what it feels like to be triggered.

What are you talking about?

There's only 2 sections of the circuit wire that are different.
>>55215825
9 = ((10e3)^-1 + (2e3)^-1 + (1e3)^-1)^-1 * I
I = .0144A (if I didn't fuck up my calculation entry)
>>55215825
Parralel circuits are retarded though.
>>55216817
Seems about right
>>55216796
I'd imagine it's for educational purposes. Such as telling the student to find the current between 2 and r1 and r1 and 7. We know it's the same, but the point is to make sure the student recognizes that.
>>55216824
yeah man they're full of bloat and are for hipsters. i only use electronics made of series circuits.
>>55216791
1-4 is all the same node, 5-8 is all the same node.
>>55215825
If you need help with pic related, maybe you should drop the class and try next semester buddy...
>>55215825
seriously just drop out
if you arent willing to put in this much effort or cant figure it out you wont make it.
hint: go check the examples in the book
>>55215825
This literally at the "you look at it and you know" level. Just read the basics laws and then you can literally derive the rest. There is not much to derive in this case though.
>>55216073
Measuring Ampere in Each resistor is Even easier, it just takes more time. In parallel ciecuits its literally In=U/Rn

Hope this helps, OP!

This doesn't help people who know what they're doing. What the fuck be this
>>55217218
Mesh analysis
>>55217218
>This doesn't help people who know what they're doing
Correction: This only helps people who know what they're doing

Sure, if you like to needlessly complicate things where ohm's and kirchoff's law will do and can read chicken scratchings.

That image is second semester university level. If you don't understand that then you should drop out or give back your degree.
>>55215825
every loops has the same voltage
i1*r1 - 9 = 0
i2*r2 -9 = 0
i3*r3 -9 = 0
>>55217840
As I said, there's no need to go into that level of detail when first semester equations will do the job more concisely. On top of that, the handwritten work is chicken scratchings.
>>55217891
Oh, then I think I misunderstood you. For the case of OP you're right.
>>55217808
There's nothing wrong with having a little fun on a simple problem
