Calculating Current Through Resistors in Loop Circuit

[Fire Slayer]

Homework Statement

Find the current through each resistor using the rules for series and parallel resistors and kirchhoff's rules

there is a loop circut with three resistors in parallel, two on top and one on bottom, then one more in series outside of it. It's all attached to a 15 volt cell

The Attempt at a Solution

I can't figure out how to find the different currents. Using the rules for series I can find a current through the whole thing, but not how much is running through each resistor. Help?

What are the resistances of each resistor? Also, your word schematic of the circuit is unclear. If you combine all parallel resistors into equivalent single resistors so that you have a bunch of series resistors, you know by kirchhoffs current law that the current flowing through each of these equivalent resistances is the same. Use the voltage law to find the current through each parallel resistor.
