Understanding Current Flow in Two Loops

Click For Summary
SUMMARY

The discussion centers on the behavior of current in two loops of an electrical circuit when different currents are present. It is established that no current can flow outside the loops if the terminals a-b are open circuited, as a complete, closed circuit is necessary for current flow. The application of Kirchhoff's Voltage Law (KVL) is recommended to analyze the voltages in each loop, leading to the calculation of voltages V1 and V2, with the final voltage being 15 volts. This approach provides a definitive method for understanding current flow in complex circuits.

PREREQUISITES
  • Understanding of Kirchhoff's Voltage Law (KVL)

Homework Statement


[PLAIN]http://img805.imageshack.us/img805/4889/adszsj.png
in two loops at the top, when different currents float in different loops, can they change their current or , while one of them is increasing, is other one decreasing..? i could not decide if the question is so easy or hard.

As long as the terminals a-b are open circuited, no current can flow outside of the loops -- there's nowhere for it to flow to. A complete, closed circuit is required for current to flow.
 
ah, okey , then i apply Kircoff Voltage Rule on the each loops and find V1 , v2 and the last one which is already 15 and add them up in terms of their sign, and the result thanks for help gneill
