Whakaoti mō A (complex solution)
\left\{\begin{matrix}A=\frac{125p}{v}\text{, }&v\neq 0\\A\in \mathrm{C}\text{, }&p=0\text{ and }v=0\end{matrix}\right.
Whakaoti mō A
\left\{\begin{matrix}A=\frac{125p}{v}\text{, }&v\neq 0\\A\in \mathrm{R}\text{, }&p=0\text{ and }v=0\end{matrix}\right.
Whakaoti mō p
p=\frac{Av}{125}

240vA=30000p
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
\frac{240vA}{240v}=\frac{30000p}{240v}
Whakawehea ngā taha e rua ki te 240v.
A=\frac{30000p}{240v}
Mā te whakawehe ki te 240v ka wetekia te whakareanga ki te 240v.
A=\frac{125p}{v}
Whakawehe 30000p ki te 240v.
240vA=30000p
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
\frac{240vA}{240v}=\frac{30000p}{240v}
Whakawehea ngā taha e rua ki te 240v.
A=\frac{30000p}{240v}
Mā te whakawehe ki te 240v ka wetekia te whakareanga ki te 240v.
A=\frac{125p}{v}
Whakawehe 30000p ki te 240v.
30000p=240Av
He hanga arowhānui tō te whārite.
\frac{30000p}{30000}=\frac{240Av}{30000}
Whakawehea ngā taha e rua ki te 30000.
p=\frac{240Av}{30000}
Mā te whakawehe ki te 30000 ka wetekia te whakareanga ki te 30000.
p=\frac{Av}{125}
Whakawehe 240vA ki te 30000.
