What is the time constant of a 0.001 microfarad capacitor and a 15000 ohm resistor connected in series in a dc circuit?
The same as the time constant of a 2.7 microfarad capacitor and a 33 ohm resistor connected in series.
How do you change time constant of capacitor?
In theory ... on paper where you have ideal components ... a capacitor all by itself doesn't have a time constant. It charges instantly. It only charges exponentially according to a time constant when it's in series with a resistor, and the time constant is (RC). Keeping the same capacitor, you change the time constant by changing the value of the resistor.

What is the time constant of a .05 microfarad capacitor and a 200 kilo ohm resistor connected in series?
The time constant of a 0.05 microfarad capacitor and a 200 K ohm resistor in series is simply their product, 0.05 times 200,000, or 10,000 microseconds, or 10 milliseconds. (Farads times ohms = seconds)
What is the time constant of a 2 mH inductor and a 200 ohm resistor connected in series?
The time constant for an RL-circuit is equal to L/R. In this case, (0.002 H)/(200 ohm).
What is the time constant of a 50mH inductor in series with a 200 ohm resistor?
The time constant (τ) of a circuit consisting of an inductor (L) and a resistor (R) in series is given by the formula τ = L/R. In this case, with L = 50mH and R = 200 ohms, the time constant would be τ = (50mH) / (200 ohms) = 0.25 milliseconds.
What are the difference between rl and RC circuit?
RL circuit consists of a resistor and an inductor connected in series, while an RC circuit consists of a resistor and a capacitor connected in series. In an RL circuit, the time constant is determined by the resistance and inductance, while in an RC circuit, the time constant is determined by the resistance and capacitance. RL circuits respond to changes in current, while RC circuits respond to changes in voltage.
What is the act of recovering energy from Capacitor?
A: It is called discharging a capacitor. The charge will follow the rules of a time constant set up by the series resistor and the capacitor. 1 time constant 63% of the charge will be reached and continue at that rate.
What is the time constant of a 20mH inductor in series with a 230 ohm resistor?
Simple...(20*10-3)/230=869 microseconds
How long does it take for a battery to charge a capacitor?
Usually a tiny fraction of a second. Actually it will depend on the characteristics of the the capacitor, and of the remaining circuit (mainly, any resistor in series). The "time constant" of a capacitor with a resistor in series to charge from 0 to a fraction of (1 - 1/e), about 68%, of its final value. This time is the product of the resistance and the capacitance. After about 5 time constant, you can consider the capacitor completely loaded for all practical purposes - i.e., it will be at the same voltage as the battery.
