Why do you have 3 primary colored electrical wires?
So they will not get mixed up.
Why earth wire is green and yellow stripped colour?
The ground conductor is colored green to be identifyable anywhere in the circuit
Is the copper screw on a lamp holder positive or negative?
Positive and negative refers to Direct Current. House wiring has alternating current. One of the terminals will be the hot, and the other neutral. The hot should go to the small metal tip inside the center of the socket, and the neutral to the metal sleeve that the bulb screws into. Typically the copper colored or darker colored screw is the hot, and the lighter colored (silver like) is the neutral, but check with a multimeter to make sure.
What do microbes need to build compost heaps?
Alternating layers of properly aerated and moistened carbon- and nitrogen-rich recyclables is the need that microbes have to build compost heaps. Dark-colored, fresh-smelling, nutrient-rich organic matter called compost or humus results from the consumption and excretion of dead, decaying, dying or living animal and plant matter by macro- and micro-organisms. The alternating brown- and green-colored layers will have to be turned at least once a week and supplementally watered to the consistency of a wrung-out sponge to prevent mildew, mold or wildfire and to support the temperature levels that befit proper composting.

What wire is positive on a table lamp?
A table lamp using AC (alternating current) does not have a positive wire, but many will color-code the wires white and black within the circuit. <><><><> As said, no positive and negative, but there IS a hot and a neutral. The hot wire may have ridges running the length of the insulation (or be colored black if separately insulated). The hot wire connects to the brass colored screw, and feeds power to the base of the bulb. Yes, will work if reversed, but is not according to electrical code. White or unridged wire connects to silver colored screw, which connects to the shell of the bulb base.

What does alternating current mean?
An alternating current (AC) is an electrical current whose magnitude and direction vary cyclically, as opposed to direct current, whose direction remains constant. The word 'alternating' itself means "changing of direction of flow". The usual waveform of an AC power circuit is very close to a sine wave because this is the way the electricity is generated in the power plants. It also allows us to efficiently transmit the energy by transforming it to higher and lower voltages. <><><> AC, or Alternating Current, does exactly what the name implies. In USA, Canada - and in other countries which use the same service frequency - the direction of the current changes 60 times a second (also called a frequency of 60 Hertz) within the 'Hot' wire (also known as the 'Live') - often colored Black - and the Return or Common wire (technically known as the 'Neutral'), which is usually colored White. In Europe and many other areas of the world, the service frequency is 50 times a second (50 Hertz) within the 'Live' wire which is colored Brown (but on older systems it is colored Black) and the Return or Common wire (technically known as the 'Neutral'), which is colored Blue (but on older systems it is colored Black). It is the service frequency which makes the typical "humming" sound you hear from transformers or electric AC motors when they are running. <><><> During just one cycle of a single-phase alternating supply, the "live" or "hot" wire of an alternating voltage (or current) supply goes from zero to its positive peak, then back to zero, then continues on to its negative peak and back to zero again. These positive- and negative-going parts of each cycle are always voltages (or currents) relative to the "neutral" wire. A neutral wire is necessary to allow the currents to return to the alternator. In a 60 hertz supply there are 60 such cycles in each and every second. Similarly, there are 50 such cycles in each and every second in a 50 hertz supply. <><><> The good link below "AC, DC and Electrical Signals" gives a lot more information about the difference between alternating current and direct current.
Should electrical enclosures be decorated?
If you're looking for colored electrical enclosures, electrical-enclosures.com would be your best bet. They specialize in custom enclosures, because they shouldn't have to be boring.
What is the point of having different colored electrical tape?
The point of having different colored electrical tape is for highly specialized reasons, and these reasons differ from US and UK. Black electrical tape stands for Insulation for both US and UK, Green tape stands for Earth ground on the US, and Earth on the UK.

What indicates that compost is ready and ripe?
The transformation of compostable materials into organic matter is what indicates that compost is ready and ripe. The composting process leaves no colors, shapes, and sizes left other than dark-colored, fresh-smelling, nutrient-rich, soil-like humus.
