Whakaoti mō c
\left\{\begin{matrix}c=\frac{I}{5m}\text{, }&m\neq 0\\c\in \mathrm{R}\text{, }&I=0\text{ and }m=0\end{matrix}\right.
Whakaoti mō I
I=5cm
Tohaina
Kua tāruatia ki te papatopenga
5cm=I
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
5mc=I
He hanga arowhānui tō te whārite.
\frac{5mc}{5m}=\frac{I}{5m}
Whakawehea ngā taha e rua ki te 5m.
c=\frac{I}{5m}
Mā te whakawehe ki te 5m ka wetekia te whakareanga ki te 5m.
