Question

which equation is correct according to ohm’s law?
r = vi
v=\frac{i}{r}
r=\frac{i}{v}
v = ir

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. The formula is $V = IR$.

Answer:

D. $V = IR$
