# Is this network of resistors in series and parallel, the way I intended?

Do these circuit schematics accurately represent these other 2 circuit schematics, which I made using Tinkercad? If so, is the resistor network for C2 built to match the equation

1/(1/(330 + 330 + 330 + 220) + 1/(330 + 330 + 330 + 100))

Which represents one serial circuit with a combined value of 1110 ohms, and another of a combined value of 1090 ohms, both in parallel, which should give a combined ohm value at the output of the circuit of 570 ohms?

If yes, how come my multimeter reads 500 ohms at the beginning and the end of these resistor networks?

EDIT:

Solved, the 400/500 ohms is because of the tolerance.

• You have one long series chain starting at A30 and ending at C29. Mar 24, 2020 at 12:40
• @Majenko How come? The resistor at A30 is not connected to the network starting from c29? And ar ethen added in parallel at 13? Mar 24, 2020 at 12:44
• A30-|===|-A26-B26-|===|-B22-A22-|===|-A18-B18-|===|-B13-D13-|===|-D17-E17-|===|-E21-D21-|===|-D25-C25-|===|-C29 Mar 24, 2020 at 12:47
• 560 ohm and 10 ohm are common values so why all the drama? Mar 24, 2020 at 12:51
• Until you have something connecting A30 and C29 (like you have done for the column 13) you won't have anything in parallel. Mar 24, 2020 at 12:57

You yet have to connect Line 29 with Line 30.

• Thank you for you answer, Could I possibly ask you to draw the schematics for it aswell, so I can understand how the schematics relate to real life better? Mar 24, 2020 at 12:50
• @GeorgeWTrump, much better if you draw the schematics yourself, then you'll really understand properly. The schematic editor here is a breeze to use. Mar 24, 2020 at 12:57
• @TonyM Well I gave it a go at that, and made my own diagrams. I have added them to the edited question. Perhaps you could take a look at it? Mar 24, 2020 at 13:31
• @GeorgeWTrump, thanks for putting the work in. It needs to be visible in your question rather than as a link. Readers need to see it in front of them and links can break anyway. Please can you make that edit. Mar 24, 2020 at 14:08

Resistor value

What is the resistor value 570 ohm for? Does it really matter if it is that precise? If 550 ohm would suffice, just add a 330 and 220 ohm resistor to get 550 ohm.

Note that each resistor has an accuracy so probably with two 5% precision resistors you get away with 550 ohms.
