I=U/R eching

$$I = \frac{ U }{ R }$$

R uchun yechish

$$\left\{\begin{matrix}R=\frac{U}{I}\text{, }&U\neq 0\text{ and }I\neq 0\\R\neq 0\text{, }&I=0\text{ and }U=0\end{matrix}\right,$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

R qiymati 0 teng bo‘lmaydi, chunki nolga bo‘lish mumkin emas. Tenglamaning ikkala tarafini R ga ko'paytirish.

$$IR=U$$

Ikki tarafini I ga bo‘ling.

$$\frac{IR}{I}=\frac{U}{I}$$

I ga bo'lish I ga ko'paytirishni bekor qiladi.

$$R=\frac{U}{I}$$

R qiymati 0 teng bo‘lmaydi.

$$R=\frac{U}{I}\text{, }R\neq 0$$

I uchun yechish

$$I=\frac{U}{R}$$

$$R\neq 0$$
