I hope you mean the thermistor.
If so,well it does not obey Ohms law. When current flows through the thermistor its temperature start increasing which reduces the resistance of the thermistor. A reduction in resistance at the same supply voltage will cause the current to increase. Thus it's not obeying Ohms law.
No semiconductor's do not obey ohm's laws.
the vibration produced in the coil of a speaker is due to current passing through it hence it obey ohms 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!
ohms law.
30 ohmsAnswerAn incandescent lamp doesn't obey Ohm's Law, because the ratio of voltage to current changes as the supply voltage is varied. All you can say is that, when the applied voltage is 9.0 V, then the resistance will happen to be 30 ohms. If you change the applied voltage to some other value, then you will find the resistance will have changed too. Ohm's Law isn't a universal law; in fact, most materials and circuit devices do not obey Ohm's Law, and tungsten, from which lamp filaments are manufactured, is an example of a metal that does not obey Ohm's Law (we call them 'non-linear' or 'non-ohmic')
which obey ohms law ANSWER: Not all potentiometers are linear some are made to follow a logarithm function some follows an exponential function. A linear potentiometer will have a linear curve. Materials that obey Ohm's Law are called 'linear' or 'ohmic'; those that don't are called 'non-ohmic' or 'non-linear'.
In point of fact, vacuum tubes do obey Ohm's law. Everything electrical obeys Ohm's law. The reason vacuum tubes don't appear to obey the law is that not every consideration takes into account the fact that vacuum tubs have dynamicresistance. Ohm's law, as applied to "pure" ohmic resistors, requires constant resistance, which no material, no matter how good, exhibits. In the real world, you have to consider that resistance can vary along with voltage and current, and this "complicates" things.
Obey The Law was created on 1926-11-05.
To find the conductance using ohms law,you take the inverse of the resistance(/R)
You should always obey the law. Religious or not.
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!
