VVVVVVery urgent things to ask nid reply fast thanks(seriously)

hey andzy
may i have ur email address?

my mail is Ediwaru_Yong@hotmail.com thanks

Natasha! Fearless Leader will reward us handsomly when we deliver Moose, and Squirel!

 

[anzdyy]

I'm in a good mood. You should go for a walk if it's nice outside, that might improve your mood.

not the suitable for a walk.. is midnite here. and i have no time. i very frustrated now. pls.. anything or any suggestion juz write down.. wat is the advantage if the shunt resistor is connected in series and wat is the disadvantages if the shunt resistor connected in parallel connection. thanks

Ahh so it's due in the morning. Well get some sleep, tell your leader you didn't pay attention or bother reading the textbook during class. The answer can be found with Google...

So if you understood the article you would realize that all the moving coil voltmeters you will ever see besides all the ones that you won't are constructed from the moving coil in series with a resistor. You choose the value of that resistor so that when the full scale voltage is across the resistor and the meter there is 1 mA flowing. To do multiple ranges requires the relentless application of Ohm's law.

Similarly all the moving coil ammeters you will ever see, besides all the ones that you won't are constucted with a resistor in parallel with the meter coil. They are chosen so that when the full scale current flows across the two parallel branches there is exactly 1mA flowing in the moving coil.

Here is the point of the exercise. How do you make very accurate resistances with very small, and very large values? If your shunt(parallel) or series resistor is off by 1%, what does it do to the range?

Humm. repetitive, demanding and confrontational.

I'm a bee, not a fly. I'm attracted to honey, not .....

You should of paid more attention in class or read your notes/textbooks.

Poor planning on your part, does not require emergency planning on my part.

cheers

And on that note I'm going for a nice walk.

PS Posting your email will get the mail-bots attention. You never know when you'll need that fake Gucci or Rolex.

Nicely put.

er.. i am sorry i don understand your question

Don't forget the pill that will enlarge body parts that you don't even posess. Oh and let's not forget the fantastic investment opportunities to be had in Nigerian Money Transfer Schemes.

er.. i am sorry i don understand your question

Question 1: How do you make very accurate resistances with very large and very small values? This is straightforward. If you want to make a 1 MegOhm resistor, a 1% tolerance implies that the actual value could plus or minus 10,000 Ohms. If you want to make 1 milliohm resistor, then a 1% tolerance implies that the actual value can be plus or mins 10 micro ohms. The point is that there are limits on how accurately a given value of resistance can be fabricated when you get to both very large, and very small values.

Question 2: When you try to make a multirange instrument from the 0-1mA moving coil meter, the further away from that range you go the bigger the resistors will be for the voltage scale, and the samller they will be for the current scale. When the ratio of the series or parallel resistance with respect to the 500 ohms of the coil becomes large enough, or small enough it has a correspondingly greater impact on the resulting measurement.

I don't know how much plainer I could be. I think its time for me to take a walk as well. My Basset Hound Blue needs to take a whizz.

Beautifui day for a walk, refreshing.

Seems like he's given up now.

Funny thread.

Wonder if he failed or passed the assignment!!

Some morons believe the pills will make them bigger.
Or the SPAMMER says that. I doubt it. The pill is not real.

When I see a pretty girl then I get ... (censored).

I wonder if a pretty girl will make a resistor get bigger.

 

[jpanhalt]

No, but some wine will make the resistance less. John

Definitely.
Hee, hee.

for the question 1 i don really know how to make a resistance that don have tolerance or error.

 

[anzdyy]

wat is the error that possible we could find in the voltmeter

wat is the error that possible we could find in the voltmeter. if got shunt resistor ? other than the error produce by the resistance wat other more? thanks

 

[niraj_dave]

u should more explain abt it
