YES it is linear. It is a passive device classified as linear however as frequency increases its behavior will change.

What happens to its resistance when an electrical device is heated?
That will depend on the temperature coefficient of resistance of the device, which could be positive (i.e. resistance increases with increasing temperature), negative (i.e. resistance decreases with increasing temperature), or zero (i.e. resistance is unaffected by temperature changes).
Is a inductor linear device?
Inductor is a nonlinear device. since v=L di/dt.
What are the examples of non linear devices?
"A device for which the output is, within a given dynamic range, linearly proportional to the input" e.g. a spring scale is linear device for measuring weight.
Why you mention diode is a nonlinear device and transistor is a linear device?
since the diode shows its characteristics in a non linearly it is called as nonlinear element since the transistor shows its characteristics in a linear way it s called as linear element Transistors are typically operated in their linear region (such as when used in amplifier circuits), or as switches (where you will in general ignore the nonlinearity of the transistor). Transistors are typically DC biased to operate in this linear region. Diodes are not biased in this way. Strictly speaking, both are nonlinear devices, although transistors can be used in their linear operation region, while diodes are not.
Is capacitor a linear device?
Capacitors are linear components. A linear component is an electronic component that has a linear relationship with current or voltage in an electronic circuit. Resistors are the most common example of linear components, along with capacitors and inductors. Linear components refer to components whose output and input have a proportional relationship. For example, the relationship between the voltage across the metal resistance element and the current can be considered to be linear when the temperature remains unchanged. Metal conductors and electrolytes also have this characteristic. Electronic components have a lot of this relationship. Poor-quality components will appear "linear distortion" under certain circumstances, that is, in such a case, the input quantity and the output quantity no longer satisfy the linear relationship. JYH HSU(JEC) Electronics Ltd (or Dongguan Zhixu Electronic Co., Ltd.) has over 30 years in the electronic components industry. Our factories are ISO 9000 and ISO 14000 certified.

Is a Resistor a nonlinear device?
It is a linear device if it is not a wire wound resistor. These become non linear to AC at high frequencies because of their inherent inductance.
When does diode acts as resistance?
When it is forward biased and, in the case of a zener diode, when it is reverse biased as well. It just is not a linear resistance type of device, and the apparent resistance changes as a function of the applied voltage or current.
What a few example of non linear resistance?
Two examples of non linear resistance is a diode and a light bulb.
What is ac and DC resistance of a diode?
diodes follow an exponential curve meaning non linear in nature. by using Boltzmann formula an impedance can be calculated. That would be the AC Resistance the dc resistance on any device is the voltage drop divided by the dc current.
How is the resistance value for a linear resistance changed?
The resistance value for linear resistance is changed by changing the wavelength of the current or by installing additional resistors in the circuit. This restricts the amount of electricity which flows through the wiring.The resistance value for the linear resistance can be changed through strain over time. It can also be changed by changes in temperatures, such as going from hot to cold.
Define Internal Resistance?
The internal resistance of a device is the resistance in ohms of that device. It is the resistance electrons need to overcome before electricity is said to flow.
Does voltage versus current indicate a linear relationship?
Yes, provided the resistance is constant. If the resistance varies with current, then you have a non-linear circuit
Diode is linear or nonlinear?
Its a Non Linear Device.Its just an electronic switch which turns on during forward bias and off during reverese bias.That is, it gets shorted with minimum resistance and opened with infinite resistance during forward and reverse biases respectively. More over any linear device has to obey superposition therem and homogenity. A linear device is that whose output is directly propostional to input. In case of diode, output (i.e current) is not directly propostional to it input(i.e voltage across it).From it governing equation I=I' * e^(V/V') ,where I' and V' is constant ,it is absolutly clear.
The correct formula to determine how many Amps of current a device will draw is?
There is no formula it depends on the device. If the device is linear it can be ascertain but if it a non linear then it becomes quite complex
What is a difference between DC and ac resistance and expline DC resistasce?
DC is just direct current into a resistance it is a linear function. AC if the resistance is non reactive it would be the same linear function.
Why a transistor is a non linear devices?
A: THE WORD IS LINEAR. yes it is not a very linear device as a function of current
What is transducer and how it may be used to measure displacement?
Transducer is a device which convert physical signal into electrical signal ( current/voltage/resistance). for linear measurement we can use LVDT (Linear Variable Displacement Transducer/ Linear Variable Differential Transformer). and for rotary measurement we can use RVDT (Rotary Variable Differential Transformer)
