Three identical capacitors are connected with a resistor in two different ways.

Question

Three identical capacitors are connected with a resistor in two different ways. When they are connected as in part a of the drawing, the time constant to charge up this circuit is 0.36 s. What is the time constant when they are connected with the same resistor as in part b?

Explanation / Answer

3c/2*R=0.36 =>2c/3*R=0.36*4/9=0.16 the time constant when they are connected with the same resistor as in part b=0.16
