Is impossible to change the voltage across a capacitor instantly as this would produce current?

Is impossible to change the voltage across a capacitor instantly as this would produce current?
Answer : Yes, it's true that you can't change the voltage across a capacitor instantly, and here's why: A capacitor stores energy in the form of an electric field created by the separation of ... is impractical. This is why, in practice, the voltage across a capacitor changes gradually, not instantly....

What is the time constant of an inductor?

What is the time constant of an inductor?
Answer : The time constant of an inductor is a measure of how quickly the current through the inductor changes when a voltage is applied. It is a characteristic time it takes for the current to reach about 63.2% ... the smaller the resistance (\( R \)), the slower the current change (larger time constant)....
