Calculating Current Through Resistors in Loop Circuit

Click For Summary
SUMMARY

The discussion focuses on calculating the current through resistors in a loop circuit involving three parallel resistors and one series resistor connected to a 15-volt power source. Participants emphasize the application of Kirchhoff's rules, specifically Kirchhoff's Current Law (KCL) and Kirchhoff's Voltage Law (KVL), to determine the current distribution. By combining parallel resistors into equivalent resistances, users can simplify the circuit analysis and accurately calculate the current through each resistor.

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.
