Simple Kirchhoff Loop problem with inductor

Click For Summary
SUMMARY

The discussion centers on analyzing a Kirchhoff Loop problem involving an inductor and a resistor within a circuit. The participant correctly identifies the battery terminals at 10V and 0V, concluding that the voltage at point A is 5V due to the back EMF produced by the inductor. The voltage difference between points A and B is established as zero, prompting further inquiry into the behavior of voltage drops and rises in circuits involving capacitors. The participant seeks clarification on the direction of current flow and its impact on voltage changes.

PREREQUISITES

Homework Statement


Just refer to the figure. The part shown is a part of a big circuit which you and anybody else shouldn't worry about.

Homework Equations


The Attempt at a Solution



I considered the battery terminals to be at 10 and 0V respectively. So the farther end of the resistor should be at 5V. An inductor produces a back EMF, which means that along the direction of current, there is a voltage drop. Therefore, A will be at 5V. So V(a)-V(b)=0. Am I right? I would be grateful to anyone who can help me solve similar problems, especially the ones which involve capacitors too. When does the "voltage" drop and when does it rise?

First, we need to decide which way the current's flowing, although for this problem it doesn't seem to make a difference. Let's say the current goes from right to left, point B to point A. As you go across the resistor, battery, and inductor, you'll have certain voltage drops or rises. I think you forgot about the voltage drop across the battery.
 
I didn't
