Capacitors

Q1:

You could increase the time constant of an RC circuit by

A adding a resistor in parallel with the circuit resistance

B adding a capacitor in parallel with the circuit capacitance

C increasing the amplitude of the input voltage

D exchanging the position of the resistor and capacitor in the circuit

ANS:B - adding a capacitor in parallel with the circuit capacitance

Time constant is = RC.

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