Hi there,

Basically TRIAC ,SCR ,JFET , UJT all are switches.
TRIAC-stands for triode AC
SCR-silicon controlled rectifier performs the operation of
rectification and inversion
JFET-junction field effect transistor
UJT-unijunction transistor,a transistor with a single junction

the features like the operating frequency,switching
frequency are different for each one of them

Answer / ali umair khan

triac , scr are thyristors(these are edge trigerred devices
and just need a input upto desired level at gate /base and
they keep in conduction)

JFET , ujt are transistors and are level trigered devices
abnd just need a constant base /drive signal to carry
cinduction

hii can u plss explain the working principle and its appplication in simpler words....

I am stuck up with a question on appending of two arrays I am writing the code for the same, I am appending two strings this way int main() { string s1 = "Welcome to C++"; string s2 = "C++ improves the logic ability"; string s3 = s1 + s2; cout<<s3<<endl; } But if I go ahead with the integer datatype , it doesnt work int main() { int arr[4] = {2,3,4,5}; int arr1[4] = {6,7,8,9}; int arr3[9] ; arr3 = arr + arr1;//displays error arr3 = arr ++ arr1; // works properly } Can anyone please clear my doubt in this question ?
