Which of the following is an ohmic resistor? [1]

Ohmic Resistors – The conductors which obey Ohm’sm’s law are called ohmic resistors.. Examples are all metallic conductors (such as silver, aluminum, copper, iron, etc), nichrome, copper sulfate, etc.
The conductors which do not obey Ohm’s law are called Non-ohmic conductors. LED, Junction diode, Filament of a bulb are examples of non-ohmic conductors.

Ohmic & Non-Ohmic Conductors » Electronics Notes [2]

Not all conductors and electronic components follow the ideal Ohms law characteristic of a linear relationship between voltage and current. There are many examples of Ohmic conductors and non-Ohmic ones.
Ohms Law states that there is a linear relationship between voltage and current. Conductors and electronic components that follow this law are called Ohmic conductors, whereas others are called non-Ohmic conductors
In understanding the basics of electronics as well as many elements of electrical science it is necessary to understand why some electronic components and conductors are Ohmic following Ohms law and others are non-Ohmic having a non-linear relationship between voltage and current.. There are very many examples of both Ohmic and non-Ohmic conductors

Hint: There are two types of material classified based on their behavior on passing electricity through them. It is practically observed that certain materials behave differently when electric current is passed through them
The two categories are: Ohmic and non-Ohmic resistances.. Ohmic resistances: The material or resistance which obeys Ohm’s law i.e
Non-Ohmic resistances: The material or resistance which obeys Ohm’s law are said to be non-ohmic resistance. For example: A light bulb has a filament which has certain resistance due to which it converts electrical energy into light and heat energy

V-I characteristic of ohmic and non-ohmic conductors [4]

Ohm’s law states that the current flowing through the conductor is directly proportional to the potential difference across the terminal. The conductors that follow Ohm’s law are known as ohmic conductors, whereas conductors that do not follow Ohm’s law to a great extent are known as non-ohmic conductors.
While designing the electrical device, it becomes essential to check whether the conductor is ohmic or non-ohmic. We aim to provide study material notes on the V-I characteristic of ohmic and non-ohmic conductors.
All those materials that have free electrons or ions are able to conduct electricity. Free electrons are used for those electrons that are very far from the nucleus and can easily detach themselves from the atom

3.2 Ohm’s Law: Resistance and Simple Circuits [5]

By the end of this section, you will be able to do the following:. – Calculate voltages, currents, and resistances with Ohm’s law
The information presented in this section supports the following AP® learning objectives and science practices:. – 4.E.4.1 The student is able to make predictions about the properties of resistors and/or capacitors when placed in a simple circuit based on the geometry of the circuit element and supported by scientific theories and mathematical relationships
All such devices create a potential difference and are loosely referred to as voltage sources. When a voltage source is connected to a conductor, it applies a potential difference that creates an electric field

[Solved] Which one of the following devices is non-ohmic? [6]

Ohm’s law: The Current through the metallic element is directly proportional to the potential difference when the temperature remains constant.. – I ∝ V or V ∝ I or V = IR [where v= potential difference, I = current, R = resistance].
– The substance which do not obey ohm’s law is non-ohmic substance e.g. gases, crystal rectifiers, thermionic valves, transistors, semiconductors, diode, bulb filaments etc.
– The non-ohmic resistors show a curve in the graph.. – Electric heating coil – heating coils are of metals – ohmic device

What are the best methods and materials for creating low-resistance ohmic contacts in nanoscale devices? [8]

What are the best methods and materials for creating low-resistance ohmic contacts in nanoscale devices?. Ohmic contacts are essential for connecting nanoscale devices to external circuits, but they can also introduce unwanted resistance and parasitic effects that degrade device performance
Ohmic contacts are the interfaces between nanoscale devices and metal electrodes. Ideally, they should allow a linear and symmetric current-voltage relationship, meaning that the current flows equally well in both directions and is proportional to the applied voltage
These effects can increase the contact resistance, reduce the device current, and introduce noise and distortion in the device output.. To achieve ohmic contacts, you need to reduce the potential barrier and increase the carrier injection at the interface
