Contact UsIs there a physical explanation for why increasing a capacitor''s ...
A larger capacitor has more energy stored in it for a given voltage than a smaller capacitor does. Adding resistance to the circuit decreases the amount of current that flows through it. Both of these effects act to reduce the rate at which the capacitor''s stored energy is dissipated, which increases the value of the circuit''s time constant.
