SUMMARY

The discussion centers on the behavior of current in a circuit with a 12V source and a 4k ohm resistor when a short circuit is introduced by making an inductor behave as a short for an infinite duration. It is established that the current will preferentially take the path of least resistance, which is through the short circuit, effectively bypassing the 12V and 4k ohm resistor. The resistance of a short circuit is considered to be zero ohms, leading to the conclusion that the current will not flow through the resistor in this scenario.

PREREQUISITES
  • Basic understanding of electrical circuits
  • Knowledge of Ohm's Law
  • Familiarity with inductors and their behavior in circuits
  • Understanding of voltage divider equations
NEXT STEPS
  • Study the behavior of inductors in DC circuits
  • Learn about short circuits and their implications in electrical design
  • Explore the voltage divider rule in more detail
  • Investigate current flow in parallel circuits
USEFUL FOR

Electrical engineers, electronics students, and anyone interested in circuit analysis and design will benefit from this discussion.

ok this is what i have, i want to know if the current would go through the 12V and 4k ohm resistor, since there is a short path (by making the inductor a short for time = infinity) would the current be lazy and take the path through the short or would it also go through the 12v and 4k ohm.

What are your thoughts? What is the resistance in Ohms for a short circuit? What is the voltage divider equation?
 
You must remember that the current through the short circuit comes from the two voltage sources.
