To answers, I'm no electrician & do not understand this kind of stuff, but my neighbors & I got into a debate about power cost & I need help.
On my powerbill the total kWh used this month is 222,
Days: 27, Avg KWh per Day is 8, & Avg Cost per Day is $0.87.
I needed some help doing some analysis.
To the nearest tenth of a cent, how much does 1 kWh cost?
-is that 0.087 cent?
I was trying to figure out in joules how energy i consume? Is there a formula and how do I do that?
-From my own research the answer I got was 799,200,000 J
Next, I wanted to find the average power consumption in Watts? (I am not sure what formula to use or how to go about this?
Also, the power company has noted that I am provided with 120 V? Based on the power consumption, what is the average current running in my house?
And in general, I was wondering how much would it cost me to leave all the lights on in the house for one day. I have 70 bulbs in my house that are all 75 watts?
Thanks!
