Quick question about resistors/schematic

[Skiguy411]

When adding a 220 ohm resistor to a 5v line, is the whole 5v line afftected by the resistor(before and after the resistor), or is it everything after that resistor affected?

 

[dighn]

everything in serires with the resistor would be affected, before or after

 

[sygyzy]

I would assume everything after the resistor.

What context? Got a schematic?

There is my best attempt to draw a schem. Would this work or not? If not, help me out please!

that looks ok i think

though the 10 ohm resistor might be a bit small, shouldn't be a big problem though. but make sure u solder that ring properly. cuz if some leds dont connect the rest might burn out

Thanks.


Second opinions welcome...I wanna make sure this is right, before I do it.

Might want to use 333 instead of the 100's, depending on the LEDs of course.

Another question.

Is it ok if the resistor is on the ground side?

 

[NutBucket]

Yes, resistor can be on either side.

just look at the LED load\power rating and adjust the resistor accordingly. you probably do not want too many volts through it. i thought LED's could take up to 24v's though? btw resistors do not have polarity. resistors in series have the same current, but voltage varies accordingly to resistance.

Depends on the LED. Actually, that's inaccurate. If the voltage across the LED is greater then about 2-3 volts (common LEDs) you'll burn it out. LEDs can only handle a certain voltage across its terminals. However, it can handle much more current, so long as the voltage remains the same.
