What are the standard abbreviations for colors in electronics? IE. R = RED....

Anyone remember the transistor theory BECky VOPINI AZAZA chart? You can draw it in your mind.

Gold, Silver, and None were pretty obvious, who needs a cheat for that?
I guess a lot changed between 1975 and 1981. In my 1975 US Navy BEE school they gave us the cheat sheet below. This chart pertains to any number of color coded electronics, not only resistors, but also computer cards like those found in the UNIVAC 1219. My classmates were of all nationalities and races. We had Israelis, Iranians and Kenyans in out classes all together.

Guess it depends on where you learned it. I heard it the first way back
around 1965. Before that I knew the colors for the resistors and could
just look at one and tell what it was for most of them. Did not have to
even think of what number each color was.

I don\'t think there is a standard. One tries to avoid ambiguous
abbreviations like Bl for blue and black.

I know several. But the OP wasn\'t asking about color code, he was asking
about color abbreviations. R for Red; G for Green etc.

 I think this may help you understand, and why, each must be measured
differently.

The resistance of a capacitor is an entirely different thing, and
amounts to the leakage current measured through the dielectric with
a voltage across it.
In terms of goodness, the lower the ESR and the higher the
resistance the better.

Could you please clarify that a bit? I am only an
inbred from Maine and I did quite get that one.
If you take an electronic device, even something simple like a battery
there are still losses inside the device from the wiring, connections and
other electrochemical stuff going on inside the device.
Those internal losses are what\'s called ESR. For instance, if you short
out a AAA battery you will get less current than if you short out a D
cell, even though both can in theory output 1.5V. The D cell has beefier
internal construction and offers a lower internal resistance, so more
current can be drawn from it.
The tricky part is a battery, (or capacitor or anything really) is not a
plain resistor, so you can\'t measure this \"equivalent\" value with an ohm
meter, but if you could, the result would be the ESR.
In capacitors, you generally want the lowest possible ESR. A cap with a
high ESR is old, failing, cheap or just junk, and it can potentially heat
up during use, just like a resistor. Heat makes electrolytic capacitors
dry up, which increased the ESR, which make them heat up more, until they
explore or just stop being capacitors.

Right.
They turn into explorers.
