Calling out for a math whiz, please!

Hello folks,

I know zip about electricity and would rather scrub floors than
do math, so could someone help me with this problem?

I have a small appliance which runs 48 hours straight at a time.
What information do I need to figure out how much it costs to
run said device for such a period of time?
What information will I need from my electric bill to figure the
cost?

Geez, I must sound stupid. It reminds me of that nonsense
back in school. If Joe drives 66 miles per hour and Bob is driving
the opposite direction going 47 miles per hour, how much longer
will it take Bob to reach the middle destination?

I say Bob, just call me on my cell phone when you finally
get here. I'll be in the bar.

According to the box:

0.15 amps
10 watts
60 hz
Rating 110-120 V.A.C. only

Unsure what this all means. Many thanks for any assistance you can provide.

a call to the electric company with that information will supply the correct answer. don't look at me....lol

Well, I did think about that, but those lazy bums don't work at
9:22 in the evening. LOL.

Just kidding.

You need to know how much your electricity costs. It's on your bill somewhere. It is billed by the kilo-watt hour, or thousand watts per hour. It varies greatly depending on where you live, and some places (here) on what time of day.
Of the info on the appliance (required by law), the relevant info is the watts, or wattage. This is the power used,or amount of work done. In this case, not much. If your electricity is 10 cents a kilowatt hour, it would take a hundred hours to cost 10 cents. I THINK....

Oh, wow, check out this site!

Scroll down to the bottom where there is a chart. Pretty neat!

Wuvie, claypa's right......you have to find out the cost of kwh. Check your last bill, if 2000 kwhs were used and the bill is $140.00

$140.00 divided by 2000 = 7.0 cents/kwh
then
10 watt appliance on for 48 hours
10 w divided by 1000 = .01 kilowatts
.01 kilowatts X 48 = .48 kilowatts
.48 X 7 = $3.36
I THINK

If it costs 7 cents for a kilowatt hour, a 10 watt appliance uses 1 hundredth of 7 cents an hour.

Make mine a double!

I think in your last line there, it should be .48 X .07=$0.0336

The cost is .07 dollars per kWhr

I THINK....

Oops...you're right

Does that seem right?

I THINK....LOL
Now, where are Joe and Bob parked....?

I bet wuvie regrets she posted this question LOL

Didn't you just have a b'day claypa?

Yes I did, thanks for noticing... now if clay covered PA resident drives 65 mph for about ten hours outta Dodge ...and doesn't stop in any bars...lol!!

LOL
I'd have to stop, math always makes me thirsty!

Happy Belated Birthday!!!!

Thanks, fly_girl !

LOL...Now this is my kinda math. Have a glass of wine, go
to bed and wake up to the answers. Ha ha!

Seriously, thank you all for your great responses. Fly, you're a doll!

I'll check the electric bill. Based on what I've figured out thus
far, I can run five of these little devices and not fret. I honestly
thought it would be running up the electric bill out the window.

Many thanks!
