A: THE WORD IS LINEAR. yes it is not a very linear device as a function of current
it is not a passive device .y because it is used to amplify the voltage and current .so as according to the definition of active device is the device which is used to amplify the current r voltage .hence transistor is a active device.
A: A transistor needs to be biased at a point whereby it is in a linear point with respect to the load otherwise it can give an output that is non linear or clipping. so with the proper bias the circuit is stable or useful.
8volts for all electronic devices
A high signal input to a transistor amplifier gives a high signal output provided it stays linear.
Hardly ever.Ohm's Law is not an universal law, and is only true when the ratio of voltage to current is constant over a wide range of voltages and, then, only for that range of voltages. In other words, if the voltage to current ratio results in a straight-line graph. If the graph is curved, then the ratio of voltage to current is not constant, and Ohm's Law doesn't apply.So Ohm's Law only applies to metal conductors, for example, providing their temperatures remain constant for changes in current -a situation that usually doesn't occur in real life. And it most certainly doesn't apply to the non-linear parts of the voltage/current characteristic curves for diodes, etc.
In saturation region transistor acts as a non linear device i.e, there is no linear relation between input and output because in saturation region output does not change for variation in input. Whereas in other operating mode transistor acts as a linear device.
linear in active region....
A load line is used in graphic analysis of circuits, having both linear and non-linear parts, representing the constraint the other parts of the circuit put on the non-linear transistor. It represents the response of the linear circuit connected to the transistor. The DC load line describes the DC operation of a transistor graphically.
A transistor begin to conduct if the Vbe is ~.6v following an exponential curve therefore non very linear. by biasing it is possible to achieve a linear portion of the load lines
1n4007 is pn junction transistor. it is a non linear device
we will operate transistor mainly in 4 regions..namely active ,cutoff,saturation and pinch off region depending on the type of biasing. if it is under active region then transistor is a linear device.. linearity in the sense if the output is proportional to input then it is said to be linear.
A: A transistor has non linear gain. To find the gain a Q point must be specified
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.
imitation of ohms law is that it can be applied only to linear devices it cannot be allowed to non linear devices...

A: Transistor to be effective as an linear amplifier it must be operated in its linear load range. The biasing scheme is to insure that the transistor is put in its linear/load range
There are many examples of these. I would compare a linear device as a device giving a linear output as a result of the input. This can be an amplifier or simply the circuits that makes up the amplifier. A non-linear device could be a computer chip or a logic chip that is either on or off (only 2 stages) on both input and output. Some devices combine linear and non linear working modes. A typical OpAmp has got 2 inputs that can vary, where as the output is either On (close to input voltage of the circuit) or Off (close to input negative voltage or GND of the circuit) Other forms of linearities can be within a single transistor. It may have a linear voltage curve. This curve can also be non linear. This most often very dependent upon temperature.
