Lissafi na amfani da makamashin lantarki ta amfani da kayan aikin lantarki - matsaloli da mafita
1. A cikin gida, akwai fitilu 5 da ake amfani da su Watt 25 a kowace rana awanni 14 a rana, akwai firiji mai Watt 200 da ake amfani da shi awanni 24 a rana, da kuma famfon ruwa mai Watt 125 da ake amfani da shi awanni 8 a rana. Nawa ne makamashin lantarki da ake amfani da shi tsawon wata guda (kwana 30)?
An sani:
Ƙarfin fitila = 5(25) = Watt 125 kuma lokacin amfani = awanni 14 x 30 = awanni 420
Ƙarfin firiji = Watts 200 kuma lokacin amfani = Awa 24 x 30 = Awa 720
Ƙarfin famfon ruwa = Watts 125 da lokacin amfani = awanni 8 x 30 = awanni 240
Ana Neman Wutar Lantarki: An yi amfani da wutar lantarki na tsawon wata guda
Magani:
Makamashin lantarki = wutar lantarki x tazara lokaci
Kuzarin (fitila) = (Watt 125)(awanni 420) = awanni 52,500 na Watt = awanni 52,5 na Watt
Makamashi (firiji) = (Watt 200)(awanni 720) = awanni 144,000 na Watt = awanni 144 na Watt
Makamashi (famfon ruwa) = (Watt 125)(awanni 240) = awannin Watt 30,000 = awannin Watt 30
Makamashin wutar lantarki da aka yi amfani da shi na tsawon wata ɗaya = 52,5 + 144 + 30 = kilo 226,5 Watt hour = kilo 226,5 Watt hour = 226,5 kWh.

2. Gida mai amfani da kayan aikin lantarki kamar yadda aka jera a cikin tebur mai zuwa.
Nawa ne makamashin lantarki da ake amfani da shi na tsawon wata 1 (kwana 30)?
An sani:
Ƙarfin fitila = Watt 4 x 10 = Watt 40 kuma lokacin amfani = Awa 10 x 30 = Awa 300
Ƙarfin talabijin = Watt 1 x 100 = Watt 100 kuma lokacin amfani = Awa 10 x 30 = Awa 300
Ƙarfin ƙarfe = Watt 1 x 300 = Watt 300 kuma lokacin amfani = Sa'o'i 2 x 30 = Sa'o'i 60
Ana Neman: Ana amfani da makamashin lantarki na tsawon wata 1
Magani:
Makamashin lantarki = wutar lantarki x lokaci
Ƙarfin da fitila ke amfani da shi = (Watt 40)(awanni 300) = awanni 12,000 Watt = awanni 12 Watt = awanni 12 kWh
Ƙarfin da TV ke amfani da shi = (Watt 100)(awanni 300) = awanni 30,000 Watt = kilos 30 Watt sa'o'i = 30 kWh
Makamashin da ƙarfe ke amfani da shi = (Watt 300)(awanni 60) = awanni 18,000 Watt = awanni 18 Watt = awanni 18 kWh
Jimlar kuzari = 12 kWh + 30 kWh + 18 kWh = 60 kWh.

Makamashin wutar lantarki da kayan aikin wutar lantarki guda uku da ke sama ke amfani da shi shine…
A. Joule 158,400
B. 950,400 Joule
C. 5,860,800 Joule
D. 9,504,000 Joule

Wutar lantarki ta TV:
P = VI = (220 Volt) (0.3 Ampere) = 66 Volt Ampere = 66 Watt = 66 Joule / dakika
Wutar lantarki ta kwamfuta:
P = VI = (220 Volt) (0.4 Ampere) = 88 Volt Ampere = 88 Watt = 88 Joule / dakika
Ƙarfin wutar lantarki na famfon ruwa:
P = VI = (220 Volt) (0.5 Ampere) = 110 Volt Ampere = 110 Watt = 110 Joule / dakika
Tazarar lokaci:
Awa 10 = daƙiƙa 10 x 3600 = daƙiƙa 36,000
Awa 6 = daƙiƙa 6 x 3600 = daƙiƙa 21600
Awa 4 = daƙiƙa 4 x 3600 = daƙiƙa 14400
Makamashin lantarki = wutar lantarki x lokaci
Makamashin wutar lantarki da TV ke amfani da shi = Joules 66/daƙiƙa x daƙiƙa 36,000 = Joules 2,376,000
Makamashin wutar lantarki da kwamfuta ke amfani da shi = Joules 88/daƙiƙa x daƙiƙa 21,600 = Joules 1,900,800
Makamashin wutar lantarki da famfon ruwa ke amfani da shi = Joules 110/daƙiƙa x daƙiƙa 14,400 = Joules 1,584,000
Jimlar makamashin lantarki:
Joules 2,376,000 + Joules 1,900,800 + Joules 1,584,000 = Joules 5,860,800

4. Iyali suna amfani da makamashin lantarki na tsawon wata ɗaya (kwana 30) don kayan aiki kamar yadda yake a cikin tebur mai zuwa!
Wutar lantarki ta injin wanki, TV da AC sune…
Magani:
Makamashin wutar lantarki na injin wanki = 12 kWh = Watt 12,000 awa, lokacin amfani = awanni 2 x 30 = awanni 60
Wutar lantarki ta talabijin = 19.2 kWh = awa 19,200 Watt, lokacin amfani = awa 8 x 30 = awa 240
Makamashin wutar lantarki na AC = 72 kWh = awanni 72,000 na Watt, lokacin amfani = awanni 6 x 30 = awanni 180
Wutar lantarki = makamashin lantarki / lokaci
Wutar lantarki ta injin wanki = Watt 12,000 awa / awanni 60 = Watt 200
Talabijin mai amfani da wutar lantarki = awanni 19,200 na Watt / awanni 240 = Watts 80
Wutar lantarki ta AC = awanni 72,000 Watt / awanni 180 = Watts 400
