Question

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

Explanation:

Ohm's law states that voltage (V) is directly proportional to current (I) through a resistor (R), with the proportionality constant being resistance. The standard form of Ohm's law is \( V = IR \).

Answer:

D. \( V = IR \)
