Ukubalwa kokusetshenziswa kwamandla kagesi ngamathuluzi kagesi - izinkinga nezixazululo
1. Endlini, kunezibani ezi-5 ezingama-25 Watt ezisetshenziswa amahora ayi-14 ngosuku, isiqandisi sama-200 Watt esisetshenziswa amahora angama-24 ngosuku, kanye nephampu yamanzi engama-125 Watt esetshenziswa amahora ayi-8 ngosuku. Kusetshenziswa amandla kagesi angakanani inyanga yonke (izinsuku ezingama-30)?
Kwaziwa:
Amandla esibani = 5(25) = 125 Watt kanye nesikhathi sokusebenzisa = amahora ayi-14 x 30 = amahora angama-420
Amandla esiqandisi = 200 Watts kanye nesikhathi sokusebenzisa = 24 hours x 30 = 720 hours
Amandla epompo yamanzi = 125 Watts kanye nesikhathi sokusetshenziswa = amahora angu-8 x 30 = amahora angu-240
Kufunwa: Amandla kagesi asetshenziswe inyanga yonke
Isixazululo:
Amandla kagesi = amandla kagesi x isikhathi esiphakathi
Amandla (isibani) = (125 Watt)(amahora angu-420) = amahora angu-52,500 Watt = amahora angu-52,5 kilo Watt
Amandla (isiqandisi) = (200 Watt)(amahora angu-720) = amahora angu-144,000 Watt = amahora angu-144 kilo Watt
Amandla (ipompo yamanzi) = (125 Watt)(amahora angu-240) = amahora angu-30,000 Watt = amahora angu-30 kilogram Watt
Amandla kagesi asetshenziswe inyanga = 52,5 + 144 + 30 = 226,5 kilo Watt ihora = 226,5 kilo Watt ihora = 226,5 kWh.

2. Indlu esebenzisa amathuluzi kagesi njengoba kuboniswe kuthebula elilandelayo.
Kusetshenziswa amandla kagesi angakanani inyanga eyodwa (izinsuku ezingu-30)?
Kwaziwa:
Amandla esibani = 4 x 10 Watt = 40 Watt kanye nesikhathi sokusebenzisa = amahora ayi-10 x 30 = amahora angama-300
Amandla e-TV = 1 x 100 Watt = 100 Watt kanye nesikhathi sokusebenzisa = amahora ayi-10 x 30 = amahora angama-300
Amandla ensimbi = 1 x 300 Watt = 300 Watt kanye nesikhathi sokusebenzisa = amahora ama-2 x 30 = amahora angama-60
Kufunwa: Amandla kagesi asetshenziswa inyanga eyodwa
Isixazululo:
Amandla kagesi = amandla kagesi x isikhathi
Amandla asetshenziswa isibani = (40 Watt)(amahora angu-300) = amahora angu-12,000 Watt = 12 kilo Watt amahora = 12 kWh
Amandla asetshenziswa yi-TV = (100 Watt)(amahora angu-300) = amahora angu-30,000 Watt = amakhilogremu angu-30 Watt amahora = 30 kWh
Amandla asetshenziswa yinsimbi = (300 Watt)(amahora angu-60) = amahora angu-18,000 Watt = 18 kilo Watt amahora = 18 kWh
Amandla aphelele = 12 kWh + 30 kWh + 18 kWh = 60 kWh.

Amandla kagesi asetshenziswa amathuluzi kagesi amathathu angenhla…
A. 158,400 Joule
B. 950,400 Joule
C. 5,860,800 Joule
D. 9,504,000 Joule
Isixazululo
Amandla kagesi e-TV:
P = VI = (220 Volt)(0.3 Ampere) = 66 Volt Ampere = 66 Watt = 66 Joule/isekhondi
Amandla kagesi ekhompyutha:
P = VI = (220 Volt)(0.4 Ampere) = 88 Volt Ampere = 88 Watt = 88 Joule/isekhondi
Amandla kagesi epompo yamanzi:
P = VI = (220 Volt)(0.5 Ampere) = 110 Volt Ampere = 110 Watt = 110 Joule/isekhondi
Isikhawu sesikhathi:
Amahora ayi-10 = 10 x 3600 imizuzwana = 36,000 imizuzwana
Amahora ayi-6 = 6 x 3600 imizuzwana = 21600 imizuzwana
Amahora ayi-4 = 4 x 3600 imizuzwana = 14400 imizuzwana
Amandla kagesi = amandla kagesi x isikhathi
Amandla kagesi asetshenziswa yi-TV = 66 Joules/isekhondi x 36,000 imizuzwana = 2,376,000 Joules
Amandla kagesi asetshenziswa yikhompyutha = 88 Joules/isekhondi x 21,600 imizuzwana = 1,900,800 Joules
Amandla kagesi asetshenziswa yipompo yamanzi = 110 Joules/imizuzwana x 14,400 imizuzwana = 1,584,000 Joules
Amandla kagesi aphelele:
AmaJoules angu-2,376,000 + amaJoules angu-1,900,800 + amaJoules angu-1,584,000 = amaJoules angu-5,860,800

4. Umndeni usebenzisa amandla kagesi inyanga yonke (izinsuku ezingu-30) ngamathuluzi njengoba kuboniswe kuthebula elilandelayo!
Amandla kagesi omshini wokuwasha, i-TV kanye ne-AC…
Isixazululo:
Amandla kagesi omshini wokuwasha = 12 kWh = 12,000 Watt ihora, isikhathi sokusebenzisa = amahora ama-2 x 30 = amahora angama-60
Amandla kagesi e-TV = 19.2 kWh = 19,200 Watt ihora, isikhathi sokusebenzisa = amahora angu-8 x 30 = amahora angu-240
Amandla kagesi e-AC = 72 kWh = amahora angu-72,000 Watt, isikhathi sokusebenzisa = amahora angu-6 x 30 = amahora angu-180
Amandla kagesi = amandla kagesi / isikhathi
Amandla kagesi omshini wokuwasha = ihora lama-Watt angu-12,000 / amahora angu-60 = ama-Watt angu-200
I-TV yamandla kagesi = amahora angu-19,200 Watt / amahora angu-240 = ama-Watt angu-80
Amandla kagesi e-AC = amahora angu-72,000 Watt / amahora angu-180 = ama-Watt angu-400
