Does this look right?

It's teling you what the current is through a 1.44 ohm reistor with 12V applied.

The answer is correct. The ammeter 'shunts out' the second resistor.

You can't wire up a circuit.

You don't get amps *across* a resistor.

You're an idiot. Go learn something about Ohms Law for starters.

No !

Stop making a fool of yourself and learn something about current flow.

sinebar,

Before you start hurling epithets, you should lurk awhile to learn a little about what others know. Most, though not all, of the people that reply to posts on this group are quite knowledgable about electronics. Your statement in response to Pooh Bear "My guess is you don't know anymore about electronics than I do." is illogical; he knew you couldn't place an ammeter in parallel and get an accurate circuit current reading - you didn't. QED.

EWB is not my first choice, but it was, and still is, required by some colleges. For instance, Old Dominion University's EE and EET programs use texts that specifical present EWB examples. They also have the software available at a reduced cost (student version). The fact is, many companies are using EWB, whether we like it or not, so it may be worthwhile learning something about it.

Whether you use EWB, SPICE, or any other similar software, you still have to know something about how the test equipment is used. The virtual instruments connect to the circuit in the same way as the real instruments.

You demonstrated a gap in your knowledge, and in your understanding of the replies, by your statements and questions. You really shouldn't get so upset when someone points that out. I can't speak for everyone, but at 57, I still learn something new every day; it is what makes it worthwhile to get out of bed.

Good luck if you decide to search for knowledge. Be civil and others will usually be the same.

I liked it better than EWB.

EWB is expensive. Out of reach for the average hobbiest.

In the basics group, yes, that is too much to ask.

If you're going to post in an electronics group it's not too much to ask that you understand at least Ohm's Law and some basics about current flow in circuits.

I understand Ohms law perfectly and If you had any real knowlege, that is being able to apply what you read on the internet, perhaps you wouldn't feel the need to insult poeple. You see there is a REAL DIFFERANCE between aquired knowlege and applied knowlege and it's funny that you lurk in a BASICS NG and insult beginners. Why don't you go to electronics design and take on Sam Goldwasser or someone like him with your crap. I bet you won't will you?

Graham is still correct, in that you show a fundamental lack of the basics of electricity.

That's why I am here asking questions. However, I am more than capable of grasping Ohm's law.

--- No, you don't. You've only just learned that the current in a series circuit is everywhere the same in that circuit, but you didn't know enough before that to _not_ connect the ammeter in parallel with one of the resistors, thereby shorting that resistor out and removing it from the circuit, causing the current in the circuit to increase

---

--- I haven't read through this whole thread, so I may be mistaken, but ISTM that what's got you riled up is that you were corrected in what you think was an insulting way.

I don't think you were, and I think you were the first one to issue epithets, which is unbecoming of a neophyte. You need to realize that when you're wrong and your error is corrected and presented to you by someone who knows more than you do, that they're doing you a favor by dragging you out of the darkness.

Your reaction to being corrected was, as I see it, the reaction of someone who was shown the solution to a simple magic trick and then, instead of thanking the magician, blamed the magician because the trick was simple and you couldn't figure it out for yourself. A cheap way of getting out of debt, no?

--- "Differance"???

See what I mean?

All of a sudden you get real nasty and start spouting ridiculous recriminations designed to try to make your teacher(s) seem insignificant in order to keep from having to admit that you owe them. A cheap trick used to try to convince yourself that you could have done it without them, so you owe them nothing.

For somebody connecting an ammeter as you did, I find that hard to believe.

Graham is still correct, in that you show a fundamental lack of the basics of electricity.

ITYM there is a big difference between Knowledge and Understanding. As you demonstrate quite well.

I suppose you don't consider "stupid mother f****rs" an insult then?

The OP's fundamental misunderstanding is shown in his very first post where he says " the amp meter reports over 8A across the resistor " and then repeats the *across* comment later.

Failure to understand that current flows *through* a resistor and that

The OP would do well to study Ohm's Law followed by Kirchoff, Norton and Thevenin.

Before passing final judgment, perhaps you should. Sure the OP's question sounded naive to someone with decades of experience. However, you and even the great Pooh had to start with the basics too. I could be wrong, but I'm betting that you guys weren't born knowing this stuff inside out.

I'm thinking that the OP thought this statement was just a tad bit insulting, "You're an idiot. Go learn something about Ohms Law for starters." Personally, I wouldn't classify that as constructive criticism, but that's just me. This is S.E.B. after all.

Actually Pooh was the first to make with the childish insults and, IMO, he should have fully expected the response that he got from the OP.

Hurling petty insults probably shouldn't be confused with enlightening someone.

I don't think the OP was offended by being "corrected", I believe it was the unnecessary insults that pissed him off.

Not really, are you starting with the spelling flames again? You often end sentences with a preposition, but does anyone ever bother making a grammatical issue of that?

Let's see. I said that after the OP had already had the mistake pointed out to him and totally ignored it and gone off at a tangent.

OP " the amp meter reports over 8A across the resistor. I thought the amps would be very low across a resistor in this kind of circuit "

( re-reading it my mind boggles at what was meant by 'this kind of circuit'

- but nm )

Lacy " You can not measure current across the resistor. You need to put the ammeter in series with the circuit "

OP " That's what I thought. So the program is lying to me. He he and they want over $2000 to license it. "

Pooh " You don't get amps *across* a resistor.You're an idiot. Go learn something about Ohms Law for starters. "

I stand by my comment even it was harsh. The OP clearly doesn't understand Ohm's Law.
