No. It only applies to a very limited range of conductors that are classified as being 'linear' or 'ohmic'. Most materials are 'non-linear' or 'non-ohmic', and these do NOT obey Ohm's Law. Non-linear conductors include tungsten and non-linear devices include diodes. For Ohm's Law to apply, the ratio of voltage to current must remain constant for variations in voltage; if it doesn't, then Ohm's Law doesn't apply. Period!
What else can I help you with?
Who is Ohm and what did he discover?
Georg Simon Ohm was a German schoolmaster who discovered that for certain conductors, the ratio of voltage to current was constant for variations in voltage. He thought that this applied to all conductors, but this is not the case. In fact, Ohm's Law applies to very few conductors and, then, only under very specific conditions.
How do conductors obey the Ohm's law?
Very few conductors obey Ohm's Law, and its the rise in temperature of the conductor when current flows though it that prevents it from obeying Ohm's Law. Some alloys, such as constantan, obey Ohm's Law over a limited range because, over that range, changes in temperature don't affect their resistance. It's really time that we stopped teaching Ohm's Law, as it is not universal, and applies to very few conductors and hardly any electronic components!
Is Ohm's law states that voltage in a circuit is equal to resistance times current true or false?
True. Ohm's law states the voltage is resistance times current.
What is an exception to ohm's law?
Most conductors and electronic devices are 'exceptions' to Ohm's Law. Ohm's Law only applies when the ratio of voltage to current remains constant for variations in voltage. Materials which behave in this way are termed 'linear' or 'ohmic'. But mostmaterials do not behave in this way, and are termed 'non-linear' or 'non-ohmic'.In simple terms, if you plot a graph of voltage against current, and the result is a curve, then that material does not obey Ohm's Law.
Advantages and disadvantages of ohm's law?
advantages is:1) we are able to analyse relationship between current and voltage.2)able to give the resistance applied in circuit.there is only one limitations that is it can change its value if the circuit is left on for long time.thankyou:).
Is ohm law true for all conductors?
No. It only applies to a very limited range of conductors that are classified as being 'linear' or 'ohmic'. Most materials are 'non-linear' or 'non-ohmic', and these do NOT obey Ohm's Law. Non-linear conductors include tungsten and non-linear devices include diodes. For Ohm's Law to apply, the ratio of voltage to current must remain constant for variations in voltage; if it doesn't, then Ohm's Law doesn't apply. Period!
Do all conductors obey ohm's law give examples to justify your answer.?
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.
True or false ohm's law is a general law of nature like newtons laws?
False. Ohm's law, unlike Newton's law, is NOT a fundamental law of nature. Instead, it's a property displayed by some materials. Some materials obey Ohm's law (example, copper, iron and conductors) while others don't (non conductors). You can also compare Newton's law of Gravity with Ohm's law. Every matter (object) is able to cause gravity. There is no exception to this rule. However, not every object obeys Ohm's law. '''Ohm's law states''' that the current through a '''conductor''' between two points is directly proportional to the potential difference or voltage across the two points, and inversely proportional to the resistance between them , at a constant temperature. This is believed to hold through by i would imagine all in the scientific community. Despite some minor statistical variations it is accepted as true. Also electricity is a natural phenomenon (lightening, static) (Ohm specifies conductors, he doesnt include non-conductors) note - in non conductors current will flow given a high enough voltage, however it wont be proportional. .

According to Ohm's law if V is constant?
Ohm's Law describes the relationship between the voltage (potential difference) across the ends of some conductors and the resulting current through those conductors for variations in voltage. If the voltage is constant, then Ohm's Law is irrelevant.
How do conductors obey the Ohm's law?
Very few conductors obey Ohm's Law, and its the rise in temperature of the conductor when current flows though it that prevents it from obeying Ohm's Law. Some alloys, such as constantan, obey Ohm's Law over a limited range because, over that range, changes in temperature don't affect their resistance.

Application of other conductors which does not obey ohms law in a circuit?
Ohms law is a law; all conductors must obey it. A simple form of ohm's law is V = I / R. The only control a conductor has on this equation is in the 'R'. Super conductors, for example, have a resistance that approaches zero at certain termperatures. This does not mean that they break the law, though.AnswerOhm's Law describes a linear relationship between the potential difference across a conductor; it has nothing to do with the relationship between potential difference, current, and resistance.The equation R = E/I is derived from the definition of the ohm, and not from Ohm's Law. This equation applies whether Ohm's Law is obeyed or not.In fact, relatively few conductors obey Ohm's Law. Those that do are termed 'ohmic' or 'linear' conductors; those that don't are termed 'non-ohmic' or 'non-linear'.Simply put, if the graph representing current plotted against a varying potential difference is not linear, then it ain't obeying Ohm's Law!
What is an ohmic conductor?
ohmic conductors are those which obey ohm's law
What are ohmic and non - ohmic conductors?
ohmic conductor does obey ohm 's law. non ohmic conductor does not obey ohm's law.
Why ohm's law is not applicable in complex network?
Because Ohm's Law is only applicable on good conductor which shows linear relationship b/w voltage and resistance while in the semi conductors it shows non linear relationship, that's why Ohm's law is not applicable on semi conductors...
Is ohms law applicable to all the current carrying conductors?
Ohm's law is a linear approximation for the voltage versus current across a conductor. This approximation works very well for good conductors (like metals) as well as poor conductors (like wood), but not very well for semi-conductors (like Silicon).
What is the necessary condition for a conductor to obey ohm's law?
No. In fact, most conductors don't obey Ohm's Law.For Ohm's Law to apply, the ratio of voltage to current must remain constant for variations in voltage. For many conductors this simply doesn't happen and, for that reason, we call such conductors 'non-linear' or 'non-ohmic'.
