Calculating Current and Energy Cost for a 100W Linear Light Bulb Per Hour

How to calculate the current consumption by a linear light bulb type receiver? For example, a 100 W light bulb will eat electricity per hour? Because then, if I know how much a kilowatt hour is, I can convert it into money. And how much does such an hour cost?

Hello !!

Add the power of all devices - for example: 1 light bulb 100W, 2 bulbs 60W each, 800W heater - the power equals 1020W, i.e. 1.02 KW. Multiply by the number of operating hours and it will come out the power consumed in KWh. In the given example - 24.48 KWh / day

Good luck - DANThE

Hmm .. is the bulb really a linear receiver?
I don't really understand your question, but I'll try to answer
If the bulb is 100W, we assume that it is a linear receiver and that it is 220V. It's from the formula for power
P = U * I * cos (phi)
we get:
I = P / (U * cos (phi))
If the linear receiver is cos (phi) = 1
so I = 100/220 = 0.46 A.
Such a current flows through our idealized light bulb.

So such a bulb will "eat" for 0.46Ah :)

But it seems to me that you meant kilowatt hours from the beginning
Therefore:
The bulb is 100W or 0.1 kW
If it works for an hour - it will consume 0.1 kWh of energy.
And if 1 kWh costs PLN 0.40, an hour of bulb operation costs PLN 0.04 (not including depreciation).
The question is, where do these bills come from?
Well, the transmission fee is fixed, variable, subscription, delivery ... and 100 other things ...
I hope I helped

Well guys, that's what it was all about. And looking at it, electricity is cheap and why do we pay such bills? Is what you replaced is added to the energy we used and that gives the final fee?

Unfortunately yes. The most expensive of all these are transmission fees, etc. The worst situation is in the villages, because transmission fees are much higher.
Energy companies do not mind that farmers have to bypass their poles in the fields ... but nothing will be done about it, because our grandparents signed a consent to such a practice (because everyone wanted to have electricity at all costs).
But the worst thing is that there are no alternatives ... well, apart from own wind farms, solar plants etc ...

only for such "electricity generators" (solar wind), when I find out, a power plant that you have something like that will come and pledge these meters, as in the 90s one engineer built himself a windmill and the power plant built a meter for him, isn't that funny ??

Hyba doesn't. You only need to obtain permission from the office for such a thing, but you cannot count on your draft

Hello !!

How can they !!
If someone builds a power plant, e.g. a hydroelectric plant, he must first "sell" electricity to the energy region, and then "buy" it at a much higher price (because it is sold cheaper and pays tax on it !!!)
together with transmission charges etc ... etc ... Only electricity for use by the power plant may not be metered by meters.

In Germany, it is so that having solar cells - let's assume that we have a 2kW converter on a sunny day - we have a meter as a converter ... So we are a small power plant - such cells return after about 15 years of use. Indeed, they buy from us cheaper than they sell to us ... Here, however, they put a lot of emphasis on the environment - hence, some reliefs are possible due to the installation of such a contraption on the roof.

As for the windmill ... If it were to bring a significant profit, it would have to be really big - the issue of permits etc ...
Nowadays you can't normally put what you want on your piece of floor ... Eh ...

What a stupid thing to take money for the fact that someone will generate electricity for himself ... Just tribute nothing else. I thought that you pay the power plant only for the electricity it produces and sells to us ... It's like paying a supermarket for vegetables grown on your own backyard garden !!!
