Ho baloa ha tšebeliso ea matla a motlakase ke lisebelisoa tsa motlakase - mathata le litharollo
1. Ka tlung, ho na le mabone a 5 a sebelisoang ka li-watt tse 25 lihora tse 14 ka letsatsi, sehatsetsi sa li-watt tse 200 se sebelisoang lihora tse 24 ka letsatsi, le pompo ea metsi ea li-watt tse 125 e sebelisoang lihora tse 8 ka letsatsi. Ke matla a makae a motlakase a sebelisoang khoeli (matsatsi a 30)?
Tse tsejoang:
Matla a lebone = 5(25) = 125 Watt le nako ea ts'ebeliso = lihora tse 14 x 30 = lihora tse 420
Matla a sehatsetsi = 200 Watts le nako ea ts'ebeliso = lihora tse 24 x 30 = lihora tse 720
Matla a pompo ea metsi = 125 Watts le nako ea tšebeliso = lihora tse 8 x 30 = lihora tse 240
Ho batloa: Matla a motlakase a sebelisitsoeng khoeli kaofela
Tharollo:
Matla a motlakase = matla a motlakase x nako e sa fellang
Matla (lebone) = (125 Watt)(lihora tse 420) = Lihora tsa Watt tse 52,500 = Lihora tsa Watt tse 52,5 kilo
Matla (sehatsetsing) = (200 Watt)(lihora tse 720) = Lihora tsa Watt tse 144,000 = Lihora tsa Watt tse 144 kilo
Matla (pompo ea metsi) = (125 Watt)(lihora tse 240) = Lihora tsa Watt tse 30,000 = Lihora tsa Watt tse 30 kilo
Matla a motlakase a sebelisitsoeng ka khoeli = 52,5 + 144 + 30 = 226,5 kilo Watt hora = 226,5 kilo Watt hora = 226,5 kWh.

2. Ntlo e sebelisang lisebelisoa tsa motlakase joalo ka ha ho thathamisitsoe tafoleng e latelang.
Ho sebelisitsoe motlakase o mokae khoeling e le 'ngoe (matsatsi a 30)?
Tse tsejoang:
Matla a lebone = 4 x 10 Watt = 40 Watt le nako ea ts'ebeliso = lihora tse 10 x 30 = lihora tse 300
Matla a TV = 1 x 100 Watt = 100 Watt le nako ea ts'ebeliso = lihora tse 10 x 30 = lihora tse 300
Matla a tšepe = 1 x 300 Watt = 300 Watt le nako ea tšebeliso = lihora tse 2 x 30 = lihora tse 60
Ho batloa: Matla a motlakase a sebelisoa khoeli e le 'ngoe
Tharollo:
Matla a motlakase = matla a motlakase x nako
Matla a sebelisoang ke lebone = (40 Watt)(lihora tse 300) = Lihora tsa Watt tse 12,000 = Lihora tsa Watt tse 12 kilo = 12 kWh
Matla a sebelisoang ke TV = (100 Watt)(lihora tse 300) = Lihora tse 30,000 tsa Watt = lik'hilograma tse 30 Lihora tsa Watt = 30 kWh
Matla a sebelisoang ke tšepe = (300 Watt)(lihora tse 60) = Lihora tsa Watt tse 18,000 = Lihora tsa Watt tse 18 kilo = 18 kWh
Kakaretso ea matla = 12 kWh + 30 kWh + 18 kWh = 60 kWh.

Matla a motlakase a TV:
P = VI = (220 Volt)(0.3 Ampere) = 66 Volt Ampere = 66 Watt = 66 Joule/motsotsoana
Matla a motlakase a khomphutha:
P = VI = (220 Volt)(0.4 Ampere) = 88 Volt Ampere = 88 Watt = 88 Joule/motsotsoana
Matla a motlakase a pompo ea metsi:
P = VI = (220 Volt)(0.5 Ampere) = 110 Volt Ampere = 110 Watt = 110 Joule/motsotsoana
Nako e sa fellang:
Lihora tse 10 = metsotsoana e 10 x 3600 = metsotsoana e 36,000
Lihora tse 6 = metsotsoana e 6 x 3600 = metsotsoana e 21600
Lihora tse 4 = metsotsoana e 4 x 3600 = metsotsoana e 14400
Matla a motlakase = matla a motlakase x nako
Matla a motlakase a sebelisoang ke TV = 66 Joules/motsotsoana x 36,000 metsotsoana = 2,376,000 Joules
Matla a motlakase a sebelisoang ke khomphutha = 88 Joules/motsotswana x 21,600 metsotsoana = 1,900,800 Joules
Matla a motlakase a sebelisoang ke pompo ea metsi = 110 Joules/metsotsoana x 14,400 metsotsoana = 1,584,000 Joules
Kakaretso ea matla a motlakase:
Li-Joules tse 2,376,000 + Li-Joules tse 1,900,800 + Li-Joules tse 1,584,000 = Li-Joules tse 5,860,800

Matla a motlakase a mochini o hlatsoang liaparo, TV le AC ke…
Tharollo:
Matla a motlakase a mochini o hlatsoang = 12 kWh = 12,000 Watt hora, nako ea ts'ebeliso = lihora tse 2 x 30 = lihora tse 60
Matla a motlakase a TV = 19.2 kWh = 19,200 Watt hora, nako ea ts'ebeliso = lihora tse 8 x 30 = lihora tse 240
Matla a motlakase a AC = 72 kWh = lihora tse 72,000 Watt, nako ea ts'ebeliso = lihora tse 6 x 30 = lihora tse 180
Matla a motlakase = matla a motlakase / nako
Matla a motlakase a mochini o hlatsoang = 12,000 Watt hora / lihora tse 60 = 200 Watt
TV ea motlakase = Lihora tsa Watt tse 19,200 / Lihora tse 240 = Li-Watt tse 80
Matla a motlakase a AC = Lihora tsa Watt tse 72,000 / Lihora tse 180 = Li-Watt tse 400
