Ohm's Law - John Dunn, Consultant, Ambertec, P.E., P.C.

There are times when one can really hit the proverbial brick wall because, as we all know, electrons are smarter than people.

You might have wanted to make some electrons to go "that" way in your circuit, but if they decide to go the "other" way, you're not going to fix that just by using your powers of oratory and persuasion. When a circuit isn't working the way it was supposed to and no amount of reason, logic, analysis or transcendental meditation seems to  be leading you to a solution to the problem, you do indeed have a problem.  

 

At the following URL, http://www.eham.net/articles/7075, we find the comment "Thomas Edison admitted that he did not even understand Ohms law and overlooked this discovery."

In his day and age, I guess Edison could be forgiven for his non-understanding, but much more recently:

In this one company where I worked, call it "Company-P", an engineer who was suffering from complete exasperation on this one particular day said out loud "I give up! Ohm's Law must be wrong."

As luck would have it, one of the Company-P directors just happened by at that exact moment and upon overhearing that pronouncement, actually went and convened a meeting of the company's other top executives to discuss the patent implications of Ohm's Law being wrong.

Sometimes, in memory of that, just to remind myself, I post a sign over my desk that reads: "Ohm Was Right!"

As per my opinion Ohm's law is the only portion of my syllabus, when i was in my senior secondary who changed my life ... and see this life through physics... this is the best article i have read in that time and just because of my interest i became an engineer.. and some time i try to prove ohm's law and always it proves himself right.
