Buyer's Guide to Led and Power Supplies - Answers for the Environment
You casually stroll into your friend's new home and are taken aback by those bright lights everywhere, in addition, you step into her room and see this magnificent illuminated table with color kinetic lighting. Wishing your house was like that? If yes, then take a look at this; LED lighting is an electronic light source which is based on the semiconductor diode and when it's switched on, electrons are able to recombine with holes and energy is released in the form of light. This effect is called electroluminescence and those multi-colors on that table that you saw? Those lights are determined by the energy gap of the semiconductor.
What argument can you put forth to persuade your parents into buying that table for you? Well here it is LED power supplies have low energy consumption, are durable, smaller in size, have improved robustness and faster switching as LED's light up quicker; precisely why their value is higher! Don't let those colorful lights play with your mind, as the greatest advantage is that the color depends on a specific variable (energy gap of the semiconductor) and hence they emit light of an intended color exclusive of the help of color filters that traditional lighting requires (which might include a fair share of your wallet). Being more resourceful and evidently, having lower initial costs, it might just be the best gamble for you and your parents!
Additionally, you might want to toss in a word of the production of light per watt when it comes to these lights, which is unquestionably more than those incandescent bulbs. As for those environment savers, the wastage of energy is minimal and they do not contain mercury, unlike most fluorescent lamps.
LED outdoor power supplies are also obtainable for protected DC power for any place, wet or dry. The LED Driver is entirely encased to shut out the elements. The power supplies range in power from 30W-300W for both indoor and outdoor lighting. Moreover, aluminum coil signage is also available and powered by LED to increase the assortment from which you may want to purchase.
To add to your awareness, just like any other electronics, these LED lighting power supplies are currently more costly, on an initial capital cost basis, than most conventional lighting technologies, and are exceptionally sensitive to temperature and voltage. LED's must be supplied with the voltage over the threshold and a current below the rating. This can involve series resistors or current-regulated power supplies, and the appropriate function of the power supply is an indispensable aspect in creating utmost efficacy and endurance of the systems. If too much current passes through the semiconductor material forming the Diodes the LED will burn out!
And of course the wellbeing of the LED power supply is a prime concern, to towards overheating, cooling should take place, and the most efficient form of this is by free air convection.

Although, LED is the latest technology in the industry and may be somewhat expensive than you had thought it to be, it's undeniably worth that money! Want more information to buyer's guide to led and power supplies from UK, USA, Canada.
What is the power P2 dissipated in resistor R2?
http://farm5.static.flickr.com/4120/5445936837_aab9ebb43d_s.jpg
Three resistors are joined together across a 12 V battery (see the figure). The voltage drop across resistor R1 is 3.856 V, the current i2 through resistor R2 is 0.092 A, and the power dissipated in resistor R3 is 0.612 W. What is the power P2 dissipated in resistor R2?
the image is too small to be readable but it looks like two resistors are in parallel (probably R2 and R3) and one in series (probably R1).
if voltage drop across R1 is 3.856V and supply is 12V then voltage drop across R2 and R3 is
12-3.856=8.144V
power dissipated by R2 is
P2=8.144 V * 0.092A =0.749W
