Question
please solve 1885,1886.
A technician Ls a man who tells you things you knew before, in terms you can't understand. Reuban A. Long, Oregon Rancher sketch the input and output on the same graph, as done in class. determine the complete expression for the output. That is, write down V_out(t) throughout its period. Set up, but don't bother to evaluate the integral for the DC average of the output V_out(t). When 'a' is '+' and 'b' is '-'clearly indicate the path of positive charge flow through the diodes and resistor R_L. Repeat ) when point 'a' is and point 'b' is '+. Sketch V_cd (voltage across R_L) on the same graph as the input voltage V_ab. Repeat 8), but with diode D_2 open.Explanation / Answer
when a is +
the following takes place
D2 -Forward biased
D1 -Reverse biased
when diode is forward biased then the electrons are said to flow through it
when the diode is reverse biased the electrons doesnt flow through it.
when b is -
the following process takes place
D4- Reverse biased
D3 -Forward biased
------------------------------------------------------------------------------------------------------------------------------------
when a is -
the following process takes place'
D1-Forward biased
D2-Reverse biased
when b is +
D4-Forward biased
D3-Reverse biased
--------------------------------------------------------------------------------
1886)
open diode is one in which an open circuit in a reverse-biased diode has no current flowing through it.
D2 is open
a is +
D1 is reverse biased and D2 is open
so no current flows in the upper half
when a is -
D1 is forward biased
D2 is reverse because it is reverse biased
