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.

Is resistance a linear device?
YES it is linear. It is a passive device classified as linear however as frequency increases its behavior will change.
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.
Can a 7.5 mfd capacitor be used in place of a 5 mfd capacitor?
Sometimes. The exception is when the capacitor is used as a "timing" device. But 7.5 mfd and 5 mfd are so large that one would guess that they are not being used as timing devices.
Characteristics of relaxation oscillator?
A "Relaxation Oscillator" is an "R/C" oscillator, in which a Capacitor is charged from a DC (Direct Current) fixed voltage source, through a resistor. Connected across this Capacitor is a "device" that, initially, does NOT conduct any current. But when the Voltage on the Capacitor reaches a certain value (depending upon the characteristics of the "device") the "device" will "break down" or "avalanche", or suddenly drastically decrease in resistance. This causes the "device" to quickly start to discharge the Capacitor. However, when the Voltage across the Capacitor and its parallel connected "device' decreases with the discharge cycle, the "device" will suddenly return to its "non-conducting" state, and the Capacitor again begins to re-charge. The Capacitor again reaches the "break down" voltage of the "device", and the process continues, thus effectively creating "oscillations". One version of this circuit uses a simple Neon lamp (such as a NE-1) as the "device". Typically, the "break down" or "ignition" voltage of a neon lamp is around 70 volts. At this point, the gas in the lamp "ionizes", becoming highly conductive. However, when this voltage drops (as the lamp discharges the Capacitor) to about 50-60 volts, the lamp "goes out" (the neon gas is no longer ionized or conducting), and the Capacitor again starts to charge through the resistor. This form of the "Relaxation Oscillator" will not operate at high frequencies (such as Radio Frequencies), and was often used to just generate a "flashing light" (the Neon lamp). With the advent of semiconductors, a device called the Unijunction Transistor (UJT) was developed. It contained three leads, the Emitter, Base 1, and Base 2. The junction of the Resistor and Capacitor is connected to the Emitter, with the "bottom" of the Capacitor (and the negative side of the Voltage Source) connected to Base 1 Base 2 is connected to the positive side of the Voltage Source. Again, when the voltage on the Capacitor reaches the "break down" level, the UJT's "resistance" between the Emitter and Base 1 drastically drops, discharging the capacitor. However, when the discharging current through the UJT drops below a certain level, it again develops a high resistance between its Base 1 and the Emitter, and re-charging of the Capacitor begins again. UJT circuits can operate at higher frequencies than the Neon bulb circuit. Often a resistor is inserted between Base1 and the common or negative side of the voltage source, and the resulting discharge current produced voltage across this resistor is used to trigger other devices. Also, the voltage waveform across the Capacitor approaches a linear "sawtooth" waveform (depending on circuit component values), but not nearly as linear as other approaches. "Devices" of this type are considered to have a "negative resistance" characteristic, which is another discussion in itself.
What means by the name capacitance of a capacitor?
The capacitor is an electronic device. Capacitance is the energy stored within this device.
Is Capacitor linear or nonlinear?
A: capacitor behaves as a linear element as the current is independent of voltage across it. current (as o/p) varies as the time rate of change of voltage across it. so capacitor rarely shows appreciable non linearity, if it is operated in the specified voltage limit
What is the name of the device used for measuring the inductance of a capacitor?
A capacitor nominally has no inductance, which is lucky because there is no such device to mesure it with.
How do you use capacitor in a sentence?
Capacitor is a noun, as in a person, place or thing. It is an electrical device. Ex: The capacitor failed and has to be replaced.
Is resistance a linear device?
YES it is linear. It is a passive device classified as linear however as frequency increases its behavior will change.
The electric device which blocks DC?
It is capacitor
What is the term used to describe the ability of a device to store energy in the form of an electrical charge?
Simply put, an electronic device that stores charge is a capacitor.
How is make capacitor?
Capacitor is nothing but a storage device. It has a dielectric media in between the two electrodes. the nature of the capacitor is charging and discharging the voltage.
Can a capacitor serves as energy saver device?
no, not really
How are the terms capacitor and capacitance related?
Capacitor is the name of the device and capacitance is a measure of farads in the capacitor. Capacitance is the capacity for storing charge in the capacitor as measured in farads, micro farads or millifarads.
What is the use capacitor?
capacitor is charge holding device ,it holds charge on two plates named as +ve and -ve
What is the device that stores charge by having a specific capacitance?
capacitor
