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.

Solution

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
