What Do You Know About Electronics?

摘要

In the February issue, I made a poor attempt to find the resistance of the bridge circuit in Figure 1 as seen by the battery. I promised (later) that I would rework the solution to that problem using Maxwell's loop equations. This is it. The June 1999 issue showed the solution to that problem by using a delta/wye transform. The resistance from B to E was determined to be 25.4Ω. I said to remember that value so we can compare it to the solution by Maxwell's loop equations that follows in this article.
