5 hours ago Byjus.com Show details

No. Ohm’s law is not a universal law. This is because ohm’s law is only applicable to ohmic conductors such as iron and copper but is not applicable to non-ohmic conductors such as semiconductors. Why is Ohm’s law not applicable to semiconductors? Ohm’s law doesn’t apply to semiconducting devices because they are nonlinear devices.

And there are FAR more ‘non-linear’ than there are ‘linear’. For Ohm’s Law to be ‘universal’, then current must remain proportional to voltage for variations in voltage. In the case of tungsten, this is clearly not the case, so tungsten does NOT ‘obey’ Ohm’s Law. And it’s NOT just tungsten that doesn’t obey Ohm’s Law.

Frequently Asked Questions

Why is ohm's law not applicable to non-linear elements?

Ohm’s law is also not applicable for non – linear elements. Non-linear elements are those which do not have current exactly proportional to the applied voltage, that means the resistance value of those elements changes for different values of voltage and current.

Can an ohm circuit be a linear circuit?

The law is applicable for linear circuits. A linear circuit is also known as Ohmic Circuit where voltage to current ratio maintains a constant ratio. Ohm’s law cannot be applied to diodes, electrolytes etc. as they come under the category of non – linear circuits.

What are the terms used in Ohms Law?

The terms used in ohm’s law are voltage, current and resistance. Voltage can be defined as the pressure which tries to push the electrons through the wires in a circuit. It is the driving force to produce electricity. Voltage is measured in volts.

Is there an infinite current in ohm's law?

Looking at Ohm’s Law, when resistance is zero, if you have any finite voltage, you get an infinite current. While there’s no such thing as an infinite current in real life, if this isn’t planned, the current will be high enough to cause some damage!
