A 10 microfard capacitor is charged through a 10 ohm resistor. How long will it take for the capacitor t fully charge?
If a 10 microfarad capacitor is charged through a 10 ohm resistor, it will theoretically never reach full charge. Practically, however, it can be considered fully charged after 5 time constants. One time constant is farads times ohms, so the time constant for a 10 microfarad capacitor and a 10 ohm resistor is 100 microseconds. Full charge will be about 500 microseconds.
What is the time constant of a series rc circuit consisting of a 2000 ohm resistor and a 10 microfarad capacitor?
2*103*10-5 = 2*10-2 Seconds = 20 milliseconds
What is function of capacitor in 555 IC?
the capacitor and its associated resistor set the time constant.
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 ia series circuit?
A circuit in which elements are connected in series.For example in RLC series circuit resistor,inductor and capacitor are connected in series.
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 47 ohm resistor and a 47 microfarad capacitor?
The time-constant is the resistance times the capacitance, so that's 47 x 47 and because the capacitance is in microfarads, the answer is in microseconds.
What is the time constant of a series rc circuit consisting of a 2000 ohm resistor and a 10 microfarad capacitor?
2*103*10-5 = 2*10-2 Seconds = 20 milliseconds
When a capacitor acts as a better filter?
When it is connected to resistor
What is function of capacitor in 555 IC?

What is one time constant of a 4.7 μF capacitor in series with a 22 kΩ resistor?
The time constant of a 4.7 µF capacitor in series with a 22 KΩ resistor is about 103 ms.

Can a transistor can act like resistor capacitor inductor?
A transistor acts like a resistor when Gate is connected to Source.
What is the time constant of a 2 microfarad capacitor in series with a 2 kilo ohm resistor?
Time constant = capacitance x resistance --> farads x ohms simplifies to units of seconds. (2 x 10-6 farads) x (2 x 103 ohms) = 4 x 10-3 seconds
What Capacitor means transferring electrons from one plate of capacitor to the other?
That would be done by a resistor connected between the two plates.
Why is capacitor leakage a problem in a RC timer circuit?
Because the timing is set by the time constant of a resistor and a capacitor. With R in ohms and C in Farads, the time-constant is RC in seconds. If the capacitor leaks the timing will be wrong.
