Suppose V BB and V CE are set to produce a current i B > 0 and V CE =0 V. Then both BE and BC junctions are forward biased. The saturation region corresponds to the case where both junctions are forward biased.. As v CE increases and reaches about 0.7 V the BC junction becomes reverse biased before this the transistor is in saturation . When v CE exceeds 0.7

Initially I is proportional to V. As the current is increased the temperature of the filament increases which leads to an increase in its resistance.This then leads to the current and voltage not increasing proportionally. The same pattern is repeated when a negative P.D is applied. So in your answer just say the temperature rises rather than

Jan 28 2012 A characteristic curve is a graph that illustrates the behaviour of a given property under a particular influence. Typically on a graph the cause is plotted along the horizontal axis x axis and the effect along the vertical axis y axis . When applied to electronic devices an I V characteristic curve shows how the current flowing through
Feb 13 2022 The behaviour of a diode in a circuit is given by its I V characteristics.

When a p n junction is first cretaed diffusion of holes and electrons take place through the junction.
Feb 10 2015 Signal and rectifier diodes have the same voltage current characteristic. As far as I know the only difference is that rectifier diodes are made a bit tougher for high voltages and currents think of a rectifier circuit while signal diodes are meant for lower operating points. They both follow the Shockley equation.
Below is a graph of the I V characteristics curve of an ideal diode Ideal Diode Characteristics Curve. You can see that when the diode receives forward voltage it instantly conducts an infinite amount of current which it can supply to a circuit. When reverse voltage is fed to the diode it conducts no current at all no matter how great this

In this part it was asked to produce an i v curve for all the diodes that has been described in the components.
