Trying to teach child about ohms. Cannot find a simple chart online to show how many ohms are in Kilohms to Megohms, etc. Any help out there? Child is visual based and a chart or conversion table the has kilohms would help greatly.....
Thanks

I think you might be able to find what you need if you look for general metric conversion instead of just ohms. Check out the examples in the source list.
Tell him/her that ohms/kiloohms/megaohms uses the same multipliers as bytes/kilobytes/megabytes.

using 220 ohm resistors and 12 volts will give a VERY bright LED. that is approximately 50 ma. traditional red LED connected to 5 volt digital logic normally used 330 ohm resistors and ran at only 10 ma. However i am aware that they now make special high current blue light LEDs which possibly is what you are using. In that case your limitation is two fold. One is the current delivery capacity of your board supply, given that each LED is 50ma. Two is heat, each of your 220 ohm resistors will get pretty hot as they will dissipate 1/2 watt each (don't get the cheap small resistors, they won't handle 1/2 watt). If these are in a confined space, the cumulative effect of the heat has to be considered.

from my a-level physics i can remember that:
Giga-ohms - 1 billion (9 zeros)
Mega-ohms - 1 million (6 zeros)
Kilo-ohms - 1 thousand (3)
milli-ohms - 1 thousanth
micro - 1 millionth
there are much smaller ones eg. peta and pico ohms but these are a million millionth, and a thousand million millionth (i think)
hope this helps

The previous post is correct. You probably could not find a chart because those prefixes mean the same whether you are dealing with ohms, volts, grams, meters, or any other unit oh measure.
