*A consumer consumes 1000 watts load per hour daily for one month.Calculate The Total Energy bill of the consumer if per unit rate is 9 (In INR ,Rs, $, DHR, or Riyal etc) [Take 1 month = 30 Days]*

######
__Solution__

__Solution__

###### 1unit = 1kWh.

######
So Total kWh = 1000 x 24 x 30 = 720000 watts/hour

we Want to convert it into Units, Where is 1unit = 1kWh.

So total Consumed units. 720000/1000...... (k=kilo=1000)

Total Units = 720.

Cost of per unit is 9.

So total Cost or bill= 720 x 9 = 6480. (In INR,Rs, $, DHR, or Riyal etc)

So total Consumed units. 720000/1000...... (k=kilo=1000)

Total Units = 720.

Cost of per unit is 9.

So total Cost or bill= 720 x 9 = 6480. (In INR,Rs, $, DHR, or Riyal etc)

[Also note that…why we multiply with 24 although the daily rate is given.. It is not Daily Rates...It’s the rate Per Unit...Where 1 unit = 1 kWh (Also Called 1 =B.T.U = Board of Trade Unit)... It means...If you switched on a 1000 watt bulb for 1 hour...It mean you consumed 1000 watts for an hour... (1000 watts for 1 hour = 1kWh = 1 unit of Energy) So if the rate of unit is 5 Dollars, then you will pay 5 Dollars as a bill for your bulb]

7201000/1000= 7201. not 720. Please correct it.

ReplyDeleteThanks Dear..it was calculator error..

DeleteHellooo Vinod Sir how u Get that 7201000... 1000x24x30=720000 na... than how u get that 7201000 .. again nxt comment u said that 1000x24x30=720000 ... i'm fully confused about u r comment please explain me.... Vindos sir and Electrical Technology

DeleteDear Karthik@

DeleteVinod have corrected the above calculation...as 1000x24x30=720000...but mistakenly, we had written 7201000 instead of 720000. That's why you are confused.

1000x24x30= 720000. Not 7201000

ReplyDeleteThanks Dear..it was calculator error..

Deletehellow sir,

Deletei am subbu....i am using commercial. i am using 1 laptop and 1 fan and 1 florescent lamp ... 1 unit per cost 7 rupess..

how is to calculte per month

ssraj217@gmail.com

for how long??? i.e, how many hours u using these appliances in a day...

Delete1000*24*30/1000=720units

Delete1000 watts daily for one month (24 hrs) .. 1000w 24hours 30 days (1000wx24hx30d) =units 720

Delete1000*24*30/1000=720units

Deletethis is a very useful site.

ReplyDeletethis site is very useful for us because we learn many things from this site.

thank you for this awesome post.

good explanation but my doubt if my total consumption is 250 units then i am paying 250*4=1000 Rs. does it mean cost of 250kW is 1000Rs if my question is wrong then what is the total amount of the palnt spendng on me to supply 250 units in a month?

ReplyDeleteYes! If your consumed Units are 250 [250kWh] and your bill is Rs. 1000, then your are paying Rs. 4 per Unit Electricity.

DeleteThanks for sharing this calculation on the Average Electric Bill. I was finding it difficult to understand how the bill is calculated, based on the consumption of electricity.

ReplyDeleteMan braucht keine Befürchtungen bezüglich dieses Prozesses. Es ist extrem sicher und man ist der Beste, was es ist gewährleistet. Der Vergleich Portal https://www.prioenergie.de/gaspreisrechner kümmert sich um den gesamten Prozess der Schalt-und sorgt dafür, dass der Übergang reibungslos funktioniert.

ReplyDeletesimpel formula is E=PT

ReplyDeleteOnly for this post.....but not apply on three phase and other load calculations

DeleteAs per your statement "A consumer consumes 1000 watts daily for one month" so that equals to 1000W *30 =30000 W hence 30kwh,

ReplyDeleteIf your statement was "A consumer uses 1000W bulb (power consumption for electrical appliances is mostly stated in watt h) for 24hrs/ day for a month of 30days. then ur calculation 1000 x 24 x 30 = 720000 watts/hour is right.

Agree...

DeleteHello Rohit sir.. here in that Question we can lighted that bulb in only 1 hour na... then how u calculated that total hours(24 hrs) .. 1000x24x30.. in that Multiplication it not comes to 24hrs i think. bcoz we can lighted only 1 hour na.... please solve my Confusion ... my problem is linked with other questions also... :( :(

DeleteDear Karthik @

DeleteCheck the Question as"A consumer consumes 1000 watts load per hour daily for one month.Calculate The Total Energy bill"

So 1000W/h daily = 1000W/h x 24....(As daily mean = 24 hrs in a day.)

That's why we have multiplied it with 24.

i'm fully confused... Why u multiply with 24 hrs (1000x24x30) ... in that Question 1000 watts load per hour daily for one month.. it means we can loaded that bulb in 1 hour Only in total 30 days na... that bulb not loaded 24 hours only in one hour... then why u multiply that 24hrs.

ReplyDelete1000Watt per hour Daily = 1000W/h x 24

DeleteCheck the Question as"A consumer consumes 1000 watts load per hour daily for one month.Calculate The Total Energy bill"

So 1000W/h daily = 1000W/h x 24....(As daily mean = 24 hrs in a day.)

That's why we have multiplied it with 24.

Ohhh okay Thank u ET.... in that question load per hour daily for one month,,, but i want i'm consumes 1 hour only in whole day for One month then how much units we can consumed...

DeleteIf you mean 1000Watt only for One hour daily (take 1 month = 30 days)

Deletethe,

1000W x 1Hr x 30 Days = 30000WH = 30kWH = 30Units

Oh Nice Thank u ET.. now totally gone Confuse.. thank u very Much.. if Diff Diff watt bulbs and Heaters are using in 3, 4 hours how to calculate... Hey in this site is thier any Electrical Calculator as per India, AP Units and Tariff.

DeleteIn case of Different load.... Add all those loads and usage per hour...then multiply with 30 , if you want to find the electric bill for 0ne month.

DeleteIt's an amazing piece of writing in favor of all the web visitors; they will get benefit

ReplyDeletefrom it I am sure.

Feel free to surf to my web site; weblink

if i have 100 watt bulb and it is usage 3 hr per day in a month how does it calculate

ReplyDeleteSir, Energy using in Telecom Towers with 3Phase s/m LT service. Each phase drawing 16A, 12A, 12A respectively. Load is static. How to calculate the avg.units per day/month/bimonthly. CT ratings 20A each phase. Trivector energy meter installed.

ReplyDelete3Phase LT Connection with Trivector energy meter CT ratings 20A. Each Phase drawing 16A,12A & 12A respectively. Static load

ReplyDeleteNo Doubt This Calculation makes to save electricity but to avoid this calculation in my opinion Low Voltage Led Lighting is good option that saves 70% to 80% of Electricity.
