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

The terminals A and B in Figure 21-31 are connected to a 9.0 V battery, where R1 = 1.8 and R2 = 3.2 .

Here is diagram of the circuit: http://www.webassign.net/walker/21-30alt.gif

I must find the current flowing through every resistor on the circuit.

2. Relevant equations

V=IR

3. The attempt at a solution

So I'm completely stuck on finding the current flowing through each resistor. I already calculated the total resistance of the entire circuit by breaking up the circuit and got a correct value of .914 ohms.

I know that for the 1.8 ohm resistor and the 2.5 ohm resistor, the voltage drop is from one terminal to the other, thus it's 9 V (the voltage of the battery) and the current flowing through those two resistors is 5 amps and 3.6 amps respectively via ohm's law.

But I'm not sure how to calculate the current for the 6.3 ohm resistor, 4.8 ohm resistor, 3.2 ohm resistor, or the 8.1 ohm resistor because I'm not quite sure how to determine the voltage drop across those resistors (I know it has to be less than 9 and that the voltage drop for 3.2 ohm resistor, the 4.8 ohm resistor, and the 8.1 ohm resistor will be the same since they are in parallel and then I can just subtract that voltage drop by 9 to get the Vdrop for the 6.3 ohm resistor. But I'm stuck in regards to finding this value.

Any help is appreciated.
