If the same experiment of figure 1 comes hour repeated in the way suggested in figure 3, that is with a sure number (n) of diode DN it connects to you in series between they, tester the measure one voltage of equal value to 0,7 V x N.
Fig. 3 - If the diode to the silicon (d) are in advanced number (n) to one, then the stabilized voltage is estimated from the product 0,7 x N.
Components:
As
an example, if the diode are four, the found voltage is of:
0,7
V x 4 = 2,8 V
Obviously,
as of the rest already it has been observed previously, the value of 2,8
V is approximate. But the two described experiments interpret a concept
of fundamental importance: that one of the stabilization of voltage in a
circuit in which they can change some characteristic electrical workers.
In the case of the circuits proposals in figures 1 - 3, changing the
value of the resistance in series, introduced from the potentiometer,
changed the intensity of current distributed from the batteries and also
changed the voltage fall on finish them of the R2 resistance, but that
one on the electrodes of the diode to the D1 silicon or of with of
diode does not connect to you in series, between which, in the
first example it was worth 0,7 V, in second 2,8 V. |
