After two time constants of time have elapsed, the current in the circuit is how many times the final current?

A time constant is a measure of the speed at which a system responds to a change. It is typically denoted by the symbol "τ" and is equal to the product of the resistance and capacitance in an electronic circuit.
After two time constants have elapsed, the current in the circuit will have reached approximately 86.5% of its maximum value. This is due to the charging and discharging of the capacitor, which affects the flow of current in the circuit.
Two time constants have been empirically determined to be a reasonable amount of time for a circuit to reach a steady state. It allows for enough time for the capacitor to charge or discharge significantly, but not so much time that it becomes impractical for real-world applications.
As mentioned earlier, the time constant is equal to the product of the resistance and capacitance. Therefore, increasing either of these values will result in a longer time constant, meaning it will take longer for the circuit to reach a steady state. Conversely, decreasing these values will result in a shorter time constant.
If we continue to measure the current at regular intervals after two time constants have elapsed, we will see that it will approach the maximum value asymptotically. This means that it will never quite reach the maximum, but will get closer and closer as more time elapses.
