Ohm's law is valid if

Question

Ohm's law is valid if (A) V is directly proportional to I3 (B) the relation between V and I is non-unique (C) V is directly proportional to I2 (D) V depends on I linearly

Tardigrade Admin · Accepted Answer

According to Ohm's law V propto I or V=R I where the constant of proportionally R is called the resistance of the conductor. From the above relation it is clear that Ohm's law is valid if V depends on I linearly.

Q. Ohm's law is valid if

$V$ is directly proportional to $I^{3}$

the relation between $V$ and $I$ is non-unique

$V$ is directly proportional to $I^{2}$

$V$ depends on $I$ linearly

According to Ohm's law
$V \propto I$ or $V = R I$
where the constant of proportionally $R$ is called the resistance of the conductor.
From the above relation it is clear that Ohm's law is valid if $V$ depends on $I$ linearly.

Q. Ohm's law is valid if

V is directly proportional to I3

the relation between V and I is non-unique

V is directly proportional to I2

V depends on I linearly

According to Ohm's law V∝I or V=RI where the constant of proportionally R is called the resistance of the conductor. From the above relation it is clear that Ohm's law is valid if V depends on I linearly.

$V$ is directly proportional to $I^{3}$

the relation between $V$ and $I$ is non-unique

$V$ is directly proportional to $I^{2}$

$V$ depends on $I$ linearly

According to Ohm's law
