Tohaina
Kua tāruatia ki te papatopenga
Ib=3.9992mA
Whakareatia te 8 ki te 0.4999, ka 3.9992.
3.9992mA=Ib
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
\frac{4999m}{1250}A=Ib
He hanga arowhānui tō te whārite.
\frac{1250\times \frac{4999m}{1250}A}{4999m}=\frac{1250Ib}{4999m}
Whakawehea ngā taha e rua ki te 3.9992m.
A=\frac{1250Ib}{4999m}
Mā te whakawehe ki te 3.9992m ka wetekia te whakareanga ki te 3.9992m.
Ib=3.9992mA
Whakareatia te 8 ki te 0.4999, ka 3.9992.
bI=\frac{4999Am}{1250}
He hanga arowhānui tō te whārite.
\frac{bI}{b}=\frac{4999Am}{1250b}
Whakawehea ngā taha e rua ki te b.
I=\frac{4999Am}{1250b}
Mā te whakawehe ki te b ka wetekia te whakareanga ki te b.
