Title: _______________
LIGHT BULB WORKSHEET

Conserving the quantity of power we use is usually steered as an vital manner folks can fight issues like acid rain and world warming. Additionally it is a superb method to fight the excessive price of residing. Using Mild Emitting Diode (LED) bulbs is usually touted as one method to lower power use. These bulbs usually are not the strip lights you could have seen in class constructing and shops. LED bulbs are the scale of a standard mild bulb however have a sort of protecting over the underside a part of the bulb (see pictures beneath).

To seek out out the impression the selection of bulb has on the quantity of electrical energy we use save this worksheet to your pc as a Phrase Doc. The entire the next exercise noting that you’ll submit a number of the information to the Question Assignment and Reply discussion board on the category site by Friday of this week.:

Go to Wal-Mart, Lowes, or ACE and discover each of the next:

1. A field of regular (incandescent) delicate white mild bulbs. These have to be 60W, medium base, delicate white bulbs. They could be basic function or 2X (lengthy life) bulbs. Guarantee that they’re basic lighting bulbs and never three manner, fan, or another shade bulbs.

2. A field of LED bulbs which are the equal of 60W. Guarantee that they’re basic lighting bulbs and never three manner, fan, or dimmable bulbs.

The LED bulbs will appear like this: The conventional mild bulbs appear like this:

You will need to discover a LED that produces the equal mild of a 60 watt regular incandescent bulb.

Word that the lifetime of some bulbs is given as “yr life”. For instance 1.four yr life.
Every “yr life” is equal to three hours per day for 365 days. three x 365 = 1095 hours. So, to transform “yr life” into hours you will want to do the next: yr life x 1095 = lifetime of the bulb in hours.

After you have discovered your 2 packing containers of bulbs you don’t want to purchase them.
Take 2 images with every merchandise; One exhibiting you with the merchandise, and one shut sufficient in order that it exhibits the worth and the knowledge proven on its field. Connect (paste/insert them into the Phrase doc) the images to the tip of this worksheet.

Learn the sunshine bulb field and use the knowledge offered to finish the desk on the subsequent pages.

LIGHT BULB WORKSHEET RESULTS
SHOW ALL CALCULATIONS
A
Worth of 1 60 Watt regular incandescent mild bulb (not the pack only one bulb!) . $
B
Life time of the bulb in hours. Convert life in years to life in hours if wanted. Ask me for Help if in case you have not procrastinated hrs
C
Worth of 1 LED bulb $
D
Life time of the LED bulb in hours. Convert life in years to life in hours if wanted. See me for Help if in case you have not procrastinated hrs
E
What number of regular bulbs would you must purchase to cowl the life of 1 LED bulb?
F
The Complete price of all the traditional bulbs calculated in E can be? $
G
The overall price of the one LED was $
H
Watts (electrical energy) utilized by the LED to supply equal mild because the 60W regular bulb W
I
A 10 Watt bulb makes use of 5 extra watts power per hour than a 5 watt bulb. How far more power does the traditional bulb use per hour than the LED? W
J

Multiply the additional power used (reply to I) by the overall life in hours for the LED. This offers you the quantity of power saved through the use of ONE LED bulb in your house. Keep in mind to indicate your work!

W
Ok
Variety of mild bulbs in your house. Embody all rooms, rest room lights, lamps, followers, and many others. however not strip lights. (Dad and mom dwelling)
L

Calculate the power saved by altering all dwelling mild bulbs to LED’s (Be sure you present your calculations). Trace: You understand how a lot power is saved by one bulb –have a look at J.

W
M

Electrical energy is bought in kW not W. Convert the power saved above from Wh to kWh (÷1000)
N

The price of electrical energy is about $zero.08 per kWh. Calculate the price of this saved electrical energy (reply to M). That is how a lot cash you’ll save, over the lifetime of the bulbs, if you happen to modified your whole bulbs to LED’s. Put up this worth to the Q&A discussion board by Friday
O
Calculate the category common for the sum of money saved if solely LED bulbs had been used within the dwelling.
P

There are about 5,700 single household dwellings in Milledgeville. Altering all the bulbs in Milledgeville to LED’s would save how a lot in electrical energy prices?
Q
