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 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

An RC circuit has an equivalent resistance of 2000 ohms and a time constant of 94 ms, what is the equivalent capacitance of the circuit?

The charge q on a capacitor is given by 𝑞 = 𝑞0(1 − 𝑒−𝑘𝑡), where0q is the initialcharge, k is a constant, and t is the time. How long does it take to recharge thecapacitor to 90% of capacity if 𝑘 = 15?

In an RC circuit supplied with a d.c. voltage, what is the effect of increasing the value of the capacitor, while keeping the values of all other components the same?Select one:a.the time constant decreases because the capacitor holds more chargeb.the current takes longer to drop to zero because the capacitor holds more chargec.the current takes less time to drop to zero because the capacitor holds less charged.the time constant increases because the capacitor holds less chargee.there is no effect unless the value of the resistor is also changed

In the following, the oscilloscope shows that the voltage across C1 reaches approximately 6.9V after 700 ms and the voltage across C1 is nearly constant there after at 6.9V. What is the time constant of the circuit?
