A capacitor in an RC circuit with R = 2 ohms and C = 4 uF is being charged. The time required for the capacitor voltage to reach 63.2 percent of its steady-state value is:a.8 sb.8 usc.2 sd.2 us

Consider an initially charged RC circuit, in order to achieve a fast response (i.e. it reaches the steady-state/final state quickly due to the quick dissipation of energy stored), practically what should be the value of the time constant?  The time constant should be as low as possible.The time constant should be infinite. The time constant should be zero. The time constant should be as high as possible.

A 2.00-nF capacitor with an initial charge of 4.90 µC is discharged through a 2.21-kΩ resistor.(a) Calculate the current in the resistor 9.00 µs after the resistor is connected across the terminals of the capacitor.
