# resistors in circuits help

#1
so here's the question and answer:

So I combined R1 and R2 as well as R4 and R6 respectively using the formula for total resistance of resistors in parallel but got it wrong for some reason. any tips?

Without seeing what else you did and your working it's hard to see exactly what is wrong...
But
You don't add R4 and R6 in parallel because you have left out R5
First add R5 and R6 in series and then the result of that to R4 in parallel.
When you've done that, you have to add that result to R3 in series.
Finally add the value you got for R1 // R2 to the rest.

As above, but visually. Kinda
I'll apologise how I write my parallel equations, I always do it like that cause easy for calculator entry 😂
Rt= 1/((1/R1)+(1/R2)) basically

Ah I see, appreciate it.
