⌛ mini christmas lights

Wow. Ohms Law has been completely remodelled. Please, please, please, can I be there to watch you give a demonstration. I just loooooooove fireworks. :D

 

your really not getting it Naaling...think of it this way if a hundred bulb sting of lights had twice the resistance at its end than its beginning then the last bulb in the string would be half as bright as the first bulb in the string.

 

Sorry, but I probably learned it before you were born. :D

 

I don't see any evidence of this!!!

You either don't understand what I'm saying or you don't want to. I suspect the latter!

 

"twice the resistance at its end than its beginning" where did you get THAT rubbish?

The two strings wired together IN SERIES - get it IN SERIES! have an overall resistance double that of one string.

Do you understand the difference between PARALLEL and SERIES Connections?

Think of it this way - the electricity now has to flow through all 100 globes no just 50 when they are wired IN SERIES

 

Its simple

V=IR

has always been that way!

By the way aircraft CAN fly and ships CAN float - that's basic physics too!

I'd love to demonstrate what I'm saying, and there wouldn't be any fireworks.

 

"twice the resistance at its end than its beginning" where did you get THAT rubbish?

I am getting it from you buddy, your the one that doesn't understand series not me...your the one saying two cords together has twice the resistance as one and again if that was the case the last bulb would be half as bright as the first...

 

That doesn't make any sense at all. Thats not the way electrical circuits work at all.

 

your absolutely right it makes no sense, on that we can agree...two strings of lights in series does not have twice the resistance of a single one and the proof is that the bulbs do not dim from one end to the other.

 

If you take a string of 50 globes wired in series and join them in series to another 50 globes also wired in series, then you have 100 globes wired in series. The electricity has to flow through all of the globes. Since each globe contributes the same amount of resistance to the overall circuit then 100 globes will have twice the resistance of 50 globes.


Its amperage that blows globes - that's why fuses are measured in amps.


Given V=IR

Then I=V/R

Therefore to retain the same amperage (I) when the resistance (R) of the entire circuit is doubled the voltage (V) has to be doubled too.

I came on this forum to help the OP. I've been very careful about what I have written and I stand by it. I have no intention of getting into a shouting match with people who have no understanding of basic electronics and algebra.
