## Homework Statement

Five resistors with resistance R1 = 4.90 Ω, R2 = 7.30 Ω, R3 = 8.80 Ω, R4 = 2.70 Ω, R5 = 5.00 Ω, are connected to a battery with emf E = 8 V in the circuit shown. What is the current in resistor R1?

I also need the current through all other resistors. I know you need to use the loop rule and solve for each unknown but I can't seem to get any of them. I don't know if I'm doing my math wrong or what but it is getting very frustrating.

The red arrows are the current arrows I am trying to work with

## The Attempt at a Solution

I have tried solving for each but I get lost in the rearranging

Any help would be awsome....or maybe some easier way to go about it?
