I have to count the total current. U = 10V. R1=100 OHM. R2+R4 are connected in a row, r2 is 470 ohm and r4 is 330 ohm. r3 and r5 are connected in a row. r3 is 390OHM and r5 is 220 OHMS. r24 is connected beside r35. r1 is connected in a row with r24+r35
I assume that by "row" you mean "in series" and by "beside" you mean "in parallel". If that is the case then the following diagram illustrates your circuit:
Resistances in series simply add: R24 = R2+R4 and R35 = R3 + R5
For resistances in parallel: 1/R2345 = (1/R24) + (1/R35)
Then R1 and R2345 are in series so Rtotal = R1 + R2345
The total current is then given by I = U/Rtotal
Can you take it from there?
(You should find that I ≈ 0.0224 A)
