Tyristor is a semiconductor device having three or more junction...
Such a device acts as a switch without any bias
and can be fabricated to hav voltage ratings of several
hundred volts to current ratings of from a few
amperes to thousands of amprees ...
The family consits of scr. .tria...diac... etc...
diode is a junction of two materials ... f
for example if its a pn junction one with excessof holes and the other with excess of electrons

Answer / dinesh kumar

thyrister is high power(current ,voltage) rating device and
also it has two or three terminal device ,but pn junction
has low power rating(current ,voltage)

compare the delay in sending x-bit msg over k-hop path in ckt switched nw nin lightil loaded packet swithed nw. the ckt setup time is s per hop,the packet size is p bits n data rate is' b' bps under what condition does packet nw have lower delay?
