Kuverengwa kwekushandiswa kwesimba remagetsi nezvishandiso zvemagetsi - matambudziko nemhinduro
1. Mumba, mune marambi mashanu ane maWatts makumi maviri nemashanu anoshandiswa maawa gumi nemana pazuva, firiji ine maWatts mazana maviri nemana pazuva, uye pombi yemvura ine maWatts zana nemakumi maviri neshanu inoshandiswa maawa masere pazuva. Simba remagetsi ringani rinoshandiswa kwemwedzi (mazuva makumi matatu)?
Zvinozivikanwa:
Simba rerambi = 5(25) = 125 Watts uye nguva yekushandisa = maawa 14 x 30 = maawa 420
Simba refiriji = 200 Watts uye nguva yekushandisa = maawa makumi maviri nemana x 30 = maawa mazana manomwe nemakumi maviri
Simba repombi yemvura = 125 Watts uye nguva yekushandisa = maawa masere x 30 = maawa mazana maviri nemakumi mana
Zvinodiwa: Simba remagetsi rakashandiswa kwemwedzi
Solution:
Simba remagetsi = simba remagetsi x nguva yekupedza
Simba (rambi) = (125 Watts) (maawa 420) = maawa 52,500 Watt = maawa 52,5 Watt
Simba (firiji) = (200 Watt) (maawa 720) = maawa 144,000 Watt = maawa 144 kilo Watt
Simba (pombi yemvura) = (125 Watts) (maawa 240) = maawa 30,000 Watt = maawa 30 Watt emakiromita
Simba remagetsi rinoshandiswa kwemwedzi = 52,5 + 144 + 30 = 226,5 kilo Watt awa = 226,5 kilo Watt awa = 226,5 kWh.

2. Imba inoshandisa maturusi emagetsi sezvakanyorwa patafura inotevera.
Simba remagetsi rinoshandiswa kwemwedzi mumwe chete (mazuva makumi matatu) rakawanda sei?
Zvinozivikanwa:
Simba rerambi = 4 x 10 Watt = 40 Watt uye nguva yekushandisa = maawa gumi x 30 = maawa mazana matatu
Simba reTV = 1 x 100 Watt = 100 Watt uye nguva yekushandisa = maawa gumi x 30 = maawa mazana matatu
Simba resimbi = 1 x 300 Watt = 300 Watt uye nguva yekushandisa = maawa maviri x 30 = maawa makumi matanhatu
Zvinodiwa: Simba remagetsi rinoshandiswa kwemwedzi mumwe chete
Solution:
Simba remagetsi = simba remagetsi x nguva
Simba rinoshandiswa nerambi = (40 Watt)(maawa mazana matatu) = maawa zviuru gumi nezviviri eWatt = 12 kilo Watt maawa = 12 kWh
Simba rinoshandiswa neTV = (100 Watt)(maawa mazana matatu) = maawa zviuru makumi matatu eWatt = 30 kilos Maawa eWatt = 30 kWh
Simba rinoshandiswa nesimbi = (300 Watt)(maawa makumi matanhatu) = 18,000 Watt maawa = 18 kilo Watt maawa = 18 kWh
Simba rose = 12 kWh + 30 kWh + 18 kWh = 60 kWh.

3.
Simba remagetsi rinoshandiswa nezvishandiso zvitatu zvemagetsi zviri pamusoro apa…
A. 158,400 Joule
B. 950,400 Joule
C. 5,860,800 Joule
D. 9,504,000 Joule
mhinduro
Simba remagetsi reTV:
P = VI = (220 Volt)(0.3 Ampere) = 66 Volt Ampere = 66 Watt = 66 Joule/sekondi
Simba remagetsi rekombuta:
P = VI = (220 Volt)(0.4 Ampere) = 88 Volt Ampere = 88 Watt = 88 Joule/sekondi
Simba remagetsi repombi yemvura:
P = VI = (220 Volt)(0.5 Ampere) = 110 Volt Ampere = 110 Watt = 110 Joule/sekondi
Nguva yepakati:
Maawa gumi = 10 x 3600 masekondi = 36,000 masekondi
Maawa gumi = 6 x 3600 masekondi = 21600 masekondi
Maawa gumi = 4 x 3600 masekondi = 14400 masekondi
Simba remagetsi = simba remagetsi x nguva
Simba remagetsi rinoshandiswa neTV = 66 Joules/sekondi x 36,000 masekondi = 2,376,000 Joules
Simba remagetsi rinoshandiswa nekombiyuta = 88 Joules/sekondi x 21,600 masekondi = 1,900,800 Joules
Simba remagetsi rinoshandiswa nepombi yemvura = 110 Joules/masekondi x 14,400 masekondi = 1,584,000 Joules
Simba remagetsi rose:
MaJoules 2,376,000 + 1,900,800 MaJoules + 1,584,000 MaJoules = 5,860,800 MaJoules

4. Mhuri inoshandisa simba remagetsi kwemwedzi (mazuva makumi matatu) pakushandisa zvishandiso sezvakaratidzwa patafura inotevera!
Simba remagetsi remuchina wekuwachisa, TV neAC…
Solution:
Simba remagetsi remuchina wekuwachisa = 12 kWh = 12,000 Watt awa, nguva yekushandisa = maawa maviri x 30 = maawa makumi matanhatu
Simba remagetsi reTV = 19.2 kWh = 19,200 Watt awa, nguva yekushandisa = maawa masere x 30 = maawa mazana maviri nemakumi mana
Simba remagetsi reAC = 72 kWh = maawa 72,000 Watt, nguva yekushandisa = maawa 6 x 30 = maawa 180
Simba remagetsi = simba remagetsi / nguva
Simba remagetsi remuchina wekuwachisa = 12,000 Watt awa / maawa makumi matanhatu = 200 Watt
TV yemagetsi = maawa 19,200 Watt / maawa 240 = 80 Watts
Simba remagetsi reAC = maawa 72,000 Watt / maawa 180 = 400 Watts
