Curios Question: Wanted to know how much rate would cost me running 10W Laser Machine for 14 mins?

Hello

Welcome here, If you also wondering how much it would cost us for running certain electrical appliance at home for our small work or business and you wondering how to make those calculations to find the rate for that mins or hours of machine running assuming just its running in your home nothing else.

If you were looking for similar answer, lets dive how I have tried to find it out myself with help of latest tech programs online!

Lets Dig In!

Here how I frame my question using the data from my latest Electricity Bill (In India, I am using Tata Power the great source of electricity provider to the nation!)

Based on following data 101-300 Units Energy Charge: 5.65 rupee /kwh, RA charges 0.00 rupee /kwh, CSS charges: 0.35 rupee /kwh, Wheeling Charges : 2.21 rupee /kwh, Fixed Demand Charges: 125.00 rupees, ED 16.00%, Tose: 0.2604 rupee /kwh
If I am running a single machine of 10W laser for 14 mins how much my electricity bill would be?

Question I formed to put in the mouth of AI tool 😛

Here is how AI calculated from the above that and calculate out the result for me:

To calculate the electricity bill, we need to convert the power consumption of the machine from Watts to kilowatts and then multiply it by the energy rate per unit.


10 W = 10/1000 kW = 0.01 kW

The time period is 14 minutes, which we need to convert to hours:

14 minutes = 14/60 hours = 0.2333 hours

The total energy consumption can be calculated as:

Energy consumed = Power x Time = 0.01 kW x 0.2333 hours = 0.002333 kWh

Now, we can calculate the energy charges, demand charges, and other charges as follows:

Energy Charges = Energy consumed x Energy rate per unit
= 0.002333 kWh x 5.65 Rs/kWh = 0.0132 Rs

Fixed Demand Charges = Fixed Demand Charges per billing cycle
= 125.00 Rs (for a single machine)

Wheeling Charges = Energy consumed x Wheeling charges per unit
= 0.002333 kWh x 2.21 Rs/kWh = 0.0051 Rs

CSS Charges = Energy consumed x CSS charges per unit
= 0.002333 kWh x 0.35 Rs/kWh = 0.0008 Rs

ED Charges = Energy charges + Wheeling charges + CSS charges
= 0.0132 Rs + 0.0051 Rs + 0.0008 Rs = 0.0191 Rs

Taxes and Other Surcharges = Energy charges + Wheeling charges + CSS charges + ED charges x Tose rate
= 0.0191 Rs x 0.2604 = 0.00498 Rs

Total Electricity Bill = Energy Charges + Fixed Demand Charges + Wheeling Charges + CSS Charges + ED Charges + Taxes and Other Surcharges
= 0.0132 Rs + 125.00 Rs + 0.0051 Rs + 0.0008 Rs + 0.0191 Rs + 0.00498 Rs
= 125.043 Rs (rounded off to two decimal places)

Therefore, if you run a single 10W laser machine for 14 minutes, your electricity bill would be approximately 125.043 Rs.

Then I said Wow so nice and quick, isn’t it?

But then thought & put my attention on the Fixed Demand Charges which 125/-, would it be a for day? then I thought No its for a month, so how it would calculate for a day? it simply as you would also know this to divide in my number of days in a month, right?

So to see if AI response the result back with more in detail with assuming and consuming similar data passed before, here is reframed question I have put (in the mouth of AI tool)

can you do this divide fixed charges by month of days and return everything again?

question for AI tool

This is what it finally answered back;

Sure, to calculate the fixed demand charges per day, we can divide the monthly fixed demand charges by the number of days in the month.

Assuming a 30-day billing cycle, the fixed demand charges per day would be:

Fixed Demand Charges per day = Fixed Demand Charges per month / Number of days in the month
= 125.00 Rs / 30 days
= 4.1667 Rs per day

Now, we can calculate the updated energy charges, wheeling charges, CSS charges, ED charges, and taxes and other surcharges per unit of energy consumed, which would be:

Energy Charges = 5.65 Rs /kWh
Wheeling Charges = 2.21 Rs /kWh
CSS Charges = 0.35 Rs /kWh
ED Charges = Energy charges + Wheeling charges + CSS charges
= 5.65 Rs/kWh + 2.21 Rs/kWh + 0.35 Rs/kWh
= 8.21 Rs/kWh

Taxes and Other Surcharges = ED charges x Tose rate
= 8.21 Rs/kWh x 0.2604
= 2.1384 Rs/kWh

To calculate the total electricity bill for running a 10W laser machine for 14 minutes per day, we can use the same method as before, but now we have updated values for the fixed demand charges, ED charges, and taxes and other surcharges.

Energy consumed per day = Energy consumed per hour x Hours per day
= 0.01 kW x 0.2333 hours/day
= 0.002333 kWh/day

Energy Charges per day = Energy consumed per day x Energy rate per unit
= 0.002333 kWh/day x 5.65 Rs/kWh
= 0.0132 Rs/day

Fixed Demand Charges per day = Fixed Demand Charges per month / Number of days in the month
= 125.00 Rs / 30 days
= 4.1667 Rs/day

Wheeling Charges per day = Energy consumed per day x Wheeling charges per unit
= 0.002333 kWh/day x 2.21 Rs/kWh
= 0.0051 Rs/day

CSS Charges per day = Energy consumed per day x CSS charges per unit
= 0.002333 kWh/day x 0.35 Rs/kWh
= 0.0008 Rs/day

ED Charges per day = Energy charges per day + Wheeling charges per day + CSS charges per day
= 0.0132 Rs/day + 0.0051 Rs/day + 0.0008 Rs/day
= 0.0191 Rs/day

Taxes and Other Surcharges per day = ED charges per day x Tose rate
= 0.0191 Rs/day x 0.2604
= 0.00498 Rs/day

Total Electricity Bill per day = Energy Charges per day + Fixed Demand Charges per day + Wheeling Charges per day + CSS Charges per day + ED Charges per day + Taxes and Other Surcharges per day
= 0.0132 Rs/day + 4.1667 Rs/day + 0.0051 Rs/day + 0.0008 Rs/day + 0.0191 Rs/day + 0.00498 Rs/day
= 4.2098 Rs/day

Therefore, if you run a single 10W laser machine for 14 minutes per day, your electricity bill would be approximately 4.2098 Rs/day

Closures in JavaScript

A closure in JavaScript is a function that has access to variables in its outer scope, even after the outer function has returned. A closure is created when a function is defined inside another function and the inner function references variables in the outer function’s scope.

Closures allow you to preserve the state of a function’s variables even after the function has returned, and they can be used to create powerful and flexible functions that can be reused in different parts of your code.

Here’s a simple example of a closure in JavaScript:

function outerFunction(x) {
return function innerFunction(y) {
return x + y;
}
}

const add5 = outerFunction(5);
console.log(add5(3)); // 8

In this example, the outerFunction returns the innerFunction, which has access to the x variable in its outer scope. When we call outerFunction(5), it returns the innerFunction with x set to 5, and we assign it to the add5 variable. When we later call add5(3), it returns the result of x + y, which is 8.

Closures are an important concept in JavaScript, as they can be used to create functions that have private variables, to implement object-oriented concepts like classes and prototypes, and to manage state and data in complex applications.
