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.
a resistor that varies its resistance
thermistor varies with temperature (most materials do this)
varistor resistance goes down with voltage across it
resistance of it vary
a resistor
A load line is used in graphical analysis of nonlinear electronic circuits, representing the constraint other parts of the circuit place on a non-linear device, like a diode or transistor. It is usually drawn on a graph of the current vs the voltage in the nonlinear device, called the device's characteristic curve. A load line, usually a straight line, represents the response of a linear circuit connected to the nonlinear device in question. The operating point(s) of the circuit are the points where the characteristic curve and the load line intersect; at these points the current and voltage parameters of both parts of the circuit match
A passive device is a diode resistor coil and so forth it perform no enhancement to the circuit or act on it.
A device which operates(or function) only in one direction is called unidirectional (or unipolar) device
In its simplest use a resistor in a circuit is used to limit the amount of current flow, or to decrease the amount of voltage applied to a device. One example is you had a 12 volt battery and you need/ wanted to connect it to a device that ran on 9 volts then a resistor can be chosen to reduce the 12 volts to the 9 volts required.
diode is nonlinear device,so device from diode is also nonlinear
Very nonlinear. If you need operation approximatinglinearity, a transistor must be limited to a very narrow range of operation.
nonlinear device modulation is a process which imparts to sinusoidal two or more amplitude levels.
nonlinear narrative
Inductor is a nonlinear device. since v=L di/dt.
A resistor
RESISTOR
the device is a resistor
Because Thevenin does not work for a nonlinear network, e.g. a battery in series with a diode and resistor.
You cannot 'slow' the flow of current in a wire. What you can do, however, is to reduce its value, or to limit its upper value. The device that will do this is a resistor. If, by your question, you are asking how to reduce the rate of change in its magnitude, then you can use an inductor.
