Yes and no. At any instant they follow ohm's la. However as they are nonlinear, as signals change they deviate from the standard ohm's law that passive components follow at all times.
Another Answer
For Ohm's Law to apply, the ratio of a conductor's (or device's) voltage to resistance MUST be constant for variations in voltage. In other words, if you plotted current against voltage, for variations in voltage, then the result MUST be a straight line. Ohm's Law does not apply at a particular instant.
Hardly any material or device obeys Ohm's Law, because most produce curved lines. Transistors do not obey Ohm's Law and is described as being 'non-linear' or 'non-ohmic'.
The equation, R = V/I, widely regarded as being 'Ohm's Law' is derived, NOT from Ohm's Law, but from the definition of the ohm.
There seems hardly any credible reason to continue teaching 'Ohm's Law' as a 'law', as it applies to so few materials.

No.

Using Ohms Law, the answer is 120/0.5 = 240 Ohms.
Yes, a light bulb obeys Ohm's law since its resistance is constant as long as the voltage across it is constant. Ohm's law states that the current through a conductor is directly proportional to the voltage across it, and inversely proportional to the resistance of the conductor.
As transistors are made of semiconductors, they do notfollow Ohm's law.A: they cannot follow exactly ohms law since they are themselves no linear active devices
Not all conductors obey Ohm's Law. There are certain materials, like semiconductors and diodes, that do not follow Ohm's Law due to their nonlinear behavior. An example of a conductor that obeys Ohm's Law is a resistor, where the current through it is directly proportional to the voltage applied.
ohms law.
Everything obeys Ohm's law - antennas, cables, transformers, integrated circuits, etc.AnswerIt is not true that 'everything' obeys Ohm's Law. For a device to obey Ohm's Law, the ratio of voltage to current MUST remain constant for variations in voltage. This is why Ohm's Law is a law of constant proportionality.
That Law applies to the Gas phase.
To find the conductance using ohms law,you take the inverse of the resistance(/R)
Yes it does
Current
no
No.
ohms=amps/volts Amps= volts/ohms Volts = Amps*Ohms
