When does a thermostor obey ohm's law?
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.
How do you calculate 1.67 ohms?
ohms law.
Is ohms law heat and light?
No.
Do transformer violates ohms law?
no
Where you r not apply ohms law?
in transformer

How vacuum tubes do not obey ohms law in circuit design?
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.
Why does ohm's matter with speakers?
the vibration produced in the coil of a speaker is due to current passing through it hence it obey ohms law
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!
How do you calculate 1.67 ohms?
ohms law.
According to ohms law what is the resistance of a light if the voltage is 9.0 volts and the current is 0.30 amps?
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')
What is a linear resistor?
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'.
What is the relation of current voltage resistance to one another?
Under normal circumstances, the relationship is given by Ohm's lawvoltage = current x resistance.The ratio of voltage to current is called resistance. This is obtained from the definition of the ohm, and not (as so often stated) from Ohm's Law.If the ratio of voltage to current is constant for variations in voltage, then the load obeys Ohm's Law and is called a 'linear' or 'ohmic' load.If the ratio of voltage to current changes for variations in voltage, then the load does NOT obey Ohm's Law, and is called 'non-linear' or 'non-ohmic'. Pure metal conductors ONLY obey Ohm's Law if their temperature is held constant. No semiconductor obeys Ohm's Law.
When was Obey The Law created?
Obey The Law was created on 1926-11-05.
How do you find conductance using ohms law?
To find the conductance using ohms law,you take the inverse of the resistance(/R)
Should religious people always obey the law?
You should always obey the law. Religious or not.
What does the i stand for in ohms law?
