Ans: Yes, it is possible to increase or decrease the time constant of the capacitor. Because time constant calculations are important, and often needed, it is better to make the definition of the time constant (T) in a CR circuit: THE TIME TAKEN FOR THE VOLTAGE ACROSS A CAPACITOR TO INCREASE BY 63.2% OF THE DIFFERENCE BETWEEN ITS PRESENT AND FINAL VALUES. Therefore the 63.2% becomes a smaller and smaller voltage rise with each time constant period and although, for all practical purposes VC = E in fact VC never quite reaches the value of E. For this reason the time when VC = E cannot be accurately defined, therefore some other accurate time measurement must be used to define the time it takes for VC to reach some given level. The time constant of a resistor-capacitor series combination is defined as the time it takes for the capacitor to deplete 36.8% (for a discharging circuit) of its charge or the time it takes to reach 63.2% (for a charging circuit) of its maximum charge capacity given that it has no initial charge.
