Because the time constant is nothing but multiplication of R and C.... So if we add capacitor in parallel then the resultant capacitance increases... So timeconstant also increases...

By incresing resistence in series also can do. !

But venu, that option is not given.
If we add resistance in parallel to the circuit resistance then the resultant resistance will be decreased than before.
And we know that the time constant is the product of both are and C. Hence we need to add capacitance in parallel with the circuit capacitance.

What is time constant?

Time constant in capacitor is T=RC to increase the value of capacitor or resistor to increase time constant.

Time constant = C.R(capacitor * resistor ).
You will be that, capacitor in parallel, Ct = C1+C2+......+Cn.
Its capacitance will be increased in parallel.
Than C.R is also increased.

Time constant is = RC.
So, increasing the capacitance because it increase in parallel while resistance decrease in parallel, time constant can be increase.

Delay is directly proportional to capacitor so if include a cap. In parallel then delay increase.

What will happen if resistance is in parallel?

@Ajsal.
If we add resistor in parallel then the resistor value gets decreases and ultimately the value of time constant decreases and which is not essential.
