which equation is correct according to ohms law?\n$v = ir$\n$i=\frac{r}{v}$\n$r=\frac{i}{v}$\n$r = iv$

Explanation:

Step1: Recall Ohm's law

Ohm's law states that the voltage ($V$) across a conductor is directly proportional to the current ($I$) flowing through it and the resistance ($R$) of the conductor, expressed as $V = IR$.

Step2: Analyze each option

• Option 1: $V = IR$ is the correct form of Ohm's law.
• Option 2: $I=\frac{R}{V}$ is incorrect. From $V = IR$, we get $I=\frac{V}{R}$.
• Option 3: $R=\frac{I}{V}$ is incorrect. From $V = IR$, we get $R=\frac{V}{I}$.
• Option 4: $R = IV$ is incorrect.

Answer:

$V = IR$ (the first - option)
