Is ohms law applicable for electrolyte?

Ohm’s Law is not a universal law, and only applies to a limited range of conductors. For Ohm’s Law to apply, the ratio of voltage to current must remain constant for variations in voltage; if the ratio varies, then Ohm’s Law does not apply. Hence,ohm’s law is not applicable for electrolytes and vacuum tubes .

Which components follow ohms law?

The many substances for which Ohm’s law holds are called ohmic. These include good conductors like copper and aluminum, and some poor conductors under certain circumstances. Ohmic materials have a resistance R that is independent of voltage V and current I.

Does ohms law obey metals at low temperatures?

Ohm’s law is not universal the substance which obeys ohm’s law are known ohmic substances like metals at low temperature . Metals at high temp has high resistance and large voltage drop are not able to obey ohms law because it do not be good conductor any more.

Why Ohm’s law is not applicable to diodes and transistors?

R = V/I (ohm) Ohm’s law is not applicable for the circuits containing electronic tubes or transistors, diode etc. because such elements are not bilateral i.e. they behave in a different manner when the direction of flow of current is reversed.

Do all metals obey Ohms law?

Conductors that obey Ohm’s law are made of metal, carbon and some alloys. Any material, component, or device that obeys Ohm’s law, where the current through the device is proportional to the voltage applied, is known as an ohmic material or ohmic component.

Do metallic conductors follow Ohm’s law?

Conductors that obey Ohm’s law are made of metal, carbon and some alloys. They are called ohmic conductors. Conductors not obeying Ohm’s law are non-ohmic – their resistance changes with voltage and current. The characteristic curve for an ohmic conductor is a straight line passing through the origin, 0, of the graph.

Do all conductors follow Ohm’s law?

Not all conductors obey Ohm’s law. In fact, most conductors of electricity are non-ohmic conductors. Ohm’s law is only true for resistors whose resistance does not depend on the applied voltage, which are called ohmic devices. …
