This question may initially seem surprising, but the answer is: Yes, the time constant. The time constant is a crucial parameter that determines how quickly or slowly a system reacts to change.
The system is made up of the voltage U, which represents the differential quantity, the resistance R and the capacity C. The flux quantity is the electric current I. In the example shown below, the time constant results from τ = R C to 1 second.
A system with a small time constant reacts very quickly to changes, while a system with a large time constant reacts slowly. It therefore provides information about how quickly a state can change, be it electrical current, mechanical movement or thermal energy.
