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 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.
How do you convert voltmeter to ohmmeter?
First you will need a constant current source. Do NOT connect the voltmeter to the constant current source without the resistor to be measured already connected. Do NOT use a battery, it is a voltage source. Then follow these steps to measure a resistor:connect the voltmeter across the resistor to be measuredconnect the voltmeter-resistor combination across the constant current sourceread the voltmeter and record the voltagedisconnect the voltmeter-resistor combination from the constant current sourcedisconnect the voltmeter from the resistorcalculate the resistance from the measured voltage and current from the source with Ohm's law in this form: R = V ÷ IIts much easier to just use the ohms setting on a multimeter.
Modern electronic multimeter measures resistances by?
forcing a constant current and measuring the voltage across the unknown resistor.
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.
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 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.
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 difference between an ohmic resistor and a non-ohmic resistor?
A non-ohmic resistor doesn't have a constant resistance. A ohmic resistor has a constant resistance.
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
How do you calculate the time constant in a series resistor?
A resistor by itself has no time constant. For a circuit to have a time constant it must contain either capacitors or inductors.
What is a ballast resistor?
A ballast resistor is an electrical resistor whose resistance varies with the current passing through it, thus maintaining a constant current.
78xx regulater as a constant current source?
The 78xx regulater can be used as a constant current source, by connecting the output to the input side of a series resistor, and the "ground" to the other side of the resistor. Do not connect the "ground" to real ground - leave it floating.Since the 78xx maintains a constant voltage differential between output and ground, there would be a constant current through the resistor.
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.
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.
