What else can I help you with?
What rule of thumb is used to indicate the amount of time it will take a capacitor to charge to the source voltage if there is a resistor in series with the capacitor?
A: Mathematically speaking the capacitor will never charge to the source because it takes one time constant to reach 63% and so on but for practical uses it is assume to be fully charged in 5 time constants R X C = 1 TIME CONSTANT
What happens to the time taken for the capacitor to charge and discharge when you increase the resistance in the circuit?
It increases. The time constant of a simple RC circuit is RC, resistance times capacitance. That is the length of time it will take for the capacitor voltage to reach about 63% of a delta step change. Ratio-metrically, if you double the resistance, you will double the charge or discharge time.
When a battery is connected with a capacitor the potential difference will?
Charge the capacitor. Potential difference is a scientific term for what is more commonly called voltage. ANSWER: If big enough the battery will see a short initially and then proceed to charge the capacitor at a rate of 63% of the voltage in one time constant defined as RC For engineering purposes after 5 time the time constant the battery will and the capacitor zero potential different. The proper term should be virtual no difference.
An ideal voltage source charges capacitor in?
A: A voltage source Will charge a capacitor to 63% of its input value, The value to get there is stated a Resistance time capacitor as time. Mathematically it will never get there but engineering consider 5 times RC time constant as close enough,
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 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.
How do you figure out the charge of a capacitor?
A: from a voltage source a capacitor will charge to 63 % of the voltage in one time constant which is define the voltage source Resistance from the source time capacitor in farads. it will continue to charge at this rate indefinitely however for practical usage 5 time constant is assume to be fully charged
Each time constant of an exponential curve is equal to what percentage of the maximum amount of charge?
Each time constant of an exponential curve, particularly in the context of charging a capacitor, represents approximately 63.2% of the maximum amount of charge. This means that after one time constant, the charge on the capacitor will have reached roughly 63.2% of its final value. Subsequent time constants will continue to increase the charge asymptotically towards the maximum, approaching but never quite reaching 100%.

How long does it take to be fully charged when a 500uF capacitor is in series with a 2.7 Kohm resistor?
Equation for voltage across capacitor in series RC circuit is as follow, vc = V(1-e-t/RC) V = DC voltage source. So theoretically time taken for capacitor to charge up to V volt is INFINITY. But practically we assume 95% or 98% of source voltage as fully charge. RC is the time constant which is the time take for capacitor to charge 63%. In this case time constant is 500uF*2.7Kohm = 1.3sec Time taken to charge 95% = 3*T = 3*1.3 = 3.9sec T = time constant Time taken to charge 98% = 4*T = 4*1.3 = 5.2sec

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.
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 WOULD happen if you keep charging time shorter than time constant?
If you keep the charging time shorter than the time constant, the capacitor will not fully charge to its maximum voltage. The voltage across the capacitor will reach approximately 63% of the final value after one time constant. Therefore, if you stop charging before the capacitor fully charges, the voltage across the capacitor will be lower than expected.
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.
