NH4NO3 (heated) ----> 2H2O (g) + N2O (g)
Thanks dude!
almost every skul skips this topic. the reason being that these topics come in a question which comes as an option ALWAYS!
Bistable circuits are circuits that consist of logic gates (NOR gates from what I've learnt) that has ONE stable output for the two inputs. If you change one of the inputs (only one pulse is needed to change it), then the output flips to the other STABLE output (e.g. if it was 0 it would become 1) and if we change the other input it flops back to the original stable output (back to 0 in this case) hence one input is used to set the output while the other is used to RESET it, they are used to flip-flop the outputs from one state to another. It exhibits the signs of memory since it reverts back to its old STABLE output (as it went back to 0 from 1 after the second change of input). It is used in computer circuits since computers need to store data in binary digits (0 & 1).

Astable circuits/multivibrators consist of a number of resistors, capacitors and logic gates (NOT gate), it does not have a stable output, its output continuously changes from one to the other (e.g 0,1,0,1,0,1). If we increase the resistance and/or capacitance then the time between the changes in output becomes larger and hence the outputs change with less frequency. It is used in ticking clocks and flashing lights (indicators and toys).
Transistors are amplifiers and switches, they act as an voltage switch (they only let current pass through it when a high enough voltage/current passes through in the correct DIRECTION), they are also used as amplifiers for magnifying currents/signals.
Hope that helps
I haven't either.
However, its in the syllabus,
use of bistable circuits and how they exhibit memory.
use of astable circuits and how resistance/capacitance affects the frequency.
I read it off the internet and from the Stephen Pople book.why i cant find it in book? where can i read about them. ur explanation does not make sense to me
The problem is that bistable circuits have NOR gates that are cross coupled, their truth tables are more complex than the others!
i think i'll just pass them
thanks by the wayby the way here, i thought these gates at least required two inputs initially. I wonder how they would work, if they had to start from scratch. i mean their second input is both from the output of the other one.
Yeah, I guess I'll give them to the notes centre.i think i'll just pass them

For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
