He told you right there...

Is this a highschool physics class you are in ?

Parallel resistors in series?

Where did anyone get that from?

And no..Beleive it or not,this is a partsman apprenticeship course...why a partsman really needs to know this I'm not sure of...But I figure for me,it'll be a good thing for me to learn for wiring subs...

Now...can someone PLEASE tell me if I got that question right..for the 3rd time....simple Yes or No....

I appreciate the help guys...I really do...But like I mentioned before,when it comes to math I suck royaly!!I failed Grade 9 math,barely squeeked thru 10 and failed 11(didnt have to take grade 12 math..thank god)...

Now....Can someone explain this all to me in such a way that someone who doesnt understand one bit of this will understand it...

Thanks again guys!!U rock!!

That looks similiar to what I had in my college course.. Theivons *sp* Theory or something finally answer would be like 1/2 page to figure out something... ah well I sucked bad at that stuff.

Aaron - dood your answer is so ****ed up I don't even know where to start...

Oh yes I do.. Where the heck do you get this from:

Quote:

Seried resistors=R1=1.5ohms and R2=3.5ohms
Parallel resis.=R3=4ohm and R4=5ohm

when the questions clearly has:

Quote:

R1 is 1/2 ohm and R2 is 3/4ohm...R3 is 1/3ohm and R4 is 1/4 ohm

Now - the way I interpret the admittedly ****ty wording of this:

Quote:

R1 is 1/2 ohm and R2 is 3/4ohm(in a series circuit)with the parallel resistors R3 is 1/3ohm and R4 is 1/4 ohm

is that R1 and R2 are in series. That's simple. Figure them out first for a total of 1.25ohms.
Then what you have is 3 resistors in parallel: (R1+R2) and R3 and R4.

If the question interprets that **** wording in some other way then that is not my fault [img]tongue.gif[/img]

Actually....its two different questions....

Anyway,Thanks to Coffeyman for giving some sensible,easy to follow ideas....Had me going in a couple minutes!

Thanks!! [img]graemlins/thumb.gif[/img]

THIS is two different questions???

15:What is the total resistance in a series-parallel circuit that has the following reistors:R1 is 1/2 ohm and R2 is 3/4ohm(in a series circuit)with the parallel resistors R3 is 1/3ohm and R4 is 1/4 ohm?

WTF. Please at least attempt to make sense. [img]graemlins/freak.gif[/img]

Ok...This a completely different question than the one in very first post...they have nothing to do with each other...so therefore,they are two different questions..Maybe I should have said "Here's 'A' question I just did" rather than "Here 'THE'question I just did"....

Heres the question I just did...let me know if I'm doing it right....

Seried resistors=R1=1.5ohms and R2=3.5ohms
Parallel resis.=R3=4ohm and R4=5ohm

Here's my solution:
Rts=Resistance total series
Rtp=Resistance total parallel

Rts=1.5ohm + 3.5ohm = 5ohm

Rtp=1/4ohm + 1/5ohm= 5/20 + 4/20= 9/20= 20/9= 20 divided by 9= 2.22ohms

Rt=Rts + Rtp= 5ohm + 2.22= 7.22ohms

Is this right??

Either way,this is more or less a dead topic...Only reason I'm leaving it up is because I'm sure theres some car audio guys who are new to the terms.....Maybe tommorow I'll delete it...
