Because time constant calculations are important, and often needed, it is better to make the definition of the time constant (T) in a CR circuit: THE TIME TAKEN FOR THE VOLTAGE ACROSS A CAPACITOR TO INCREASE BY 63.2% OF THE DIFFERENCE BETWEEN ITS PRESENT AND FINAL VALUES.
When there is a steady current in the circuit, the amount of charge passing a point per unit of time is. (A) the same everywhere in the circuit. (B) greater in the 1 â¦ resistor than in the 2 â¦ resistor. (C) greater in the 2 â¦ resistor than in the 3 â¦ resistor.
