Réitigh W=VI(V)

$$W = VI(V)$$

Réitigh do I. (complex solution)

$$\left\{\begin{matrix}I=\frac{W}{V^{2}}\text{, }&V\neq 0\\I\in \mathrm{C}\text{, }&W=0\text{ and }V=0\end{matrix}\right.$$

Céimeanna chun Cothromóidí Líneacha a Réiteach

Méadaigh V agus V chun V^{2} a fháil.

$$W=V^{2}I$$

Athraigh na taobhanna ionas go mbeidh na téarmaí inathraitheacha ar fad ar an taobh clé.

$$V^{2}I=W$$

Roinn an dá thaobh faoi V^{2}.

$$\frac{V^{2}I}{V^{2}}=\frac{W}{V^{2}}$$

Má roinntear é faoi V^{2} cuirtear an iolrúchán faoi V^{2} ar ceal.

$$I=\frac{W}{V^{2}}$$

Réitigh do I.

$$\left\{\begin{matrix}I=\frac{W}{V^{2}}\text{, }&V\neq 0\\I\in \mathrm{R}\text{, }&W=0\text{ and }V=0\end{matrix}\right.$$
