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.

Why bias a transistor?
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
What is the significance of dc load line in a transistor?
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.
Is rectifier a non linear device?
diode is nonlinear device,so device from diode is also nonlinear
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
Is zener diode a linear device?
Zener diode is not a linear device... it is non-linear one. Since linear devices are those devices which have linear characteristics(V-I CHAR.), or follows the Ohm's law i.e. voltage is directly proportional to current. but in case of Zener diode ohm's law fails down. the V-I char. in both forward biased & reverse biased condition is non-linear. So. Zener diode is non-linear device
