How do you find the current through a resistor that is in parallel with 2 other nonequal resistors? I totally forgot how to do this.
as an example, if

E = 10V
R1= 5ohm
R2 = 10ohm
R3 = 15ohm

So, I know that 1/Req = 1/R1 + 1/R2 + 1/R3 = .533ohm

and also know Inet = 10V/.533ohm = 18.76A

but how do i get current going through R1?


please help, and thanks


PS --this is NOT a homework question even though i post a lot of HW questions

You have the voltage and resistance, just use Ohms law.
 


So you use ohms law for each resistor and doesn't matter if its in parallel or in series with other resistors? (thats what's confusing me)
 


Hint: You have too much information.
