(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A circuit composed of one battery and four resistors is arranged as shown in the attached pic.

E = 19 V

R1 = 12 W

R2 = 2 W

R3 = 15 W

R4 = 2 W

Calculate the current I1 through R1?

2. Relevant equations

V=IR (obviously)

3. The attempt at a solution

first i got the net current in this circuit by doing the following..

i summed resistors in series to get 14ohm on first loop and 17ohm on second loop.

then i applied resistance in parallel rule :

Req = (1/R1) + (1/R2)

= 7.69ohm = Rtotal

then I = V/R = 2.47A = total current in the circuit.

Then to get the current on the 14 ohm loopm i multiplied 2.47 by (14/17) . ( i think this is where I am erring, but cant see why this doesnt work??)

= 2.03A (wrong)

thanks for any help!
