What else can I help you with?
What is the most resistance that can be in series with the capacitor if the capacitor is to charge to at least 88 percent of its final voltage in no more than 8.0 s?
Without knowing the capacitance of the capacitor, your question cannot be answered.
Does an electric capacitor store electric charge?
Capacitors store energy in the electric field between their plates. They do not store charge, the net value of which is the same after, as before, charging (they do, however, separate charge).
What is the difference in a 5 UF and a 15 UF capacitor?
The difference between a 5 microfarad (UF) and a 15 microfarad capacitor lies in their capacitance values, which indicate their ability to store electrical charge. A 15 UF capacitor can store three times more charge than a 5 UF capacitor at the same voltage. This larger capacitance makes the 15 UF capacitor more suitable for applications requiring higher energy storage or filtering capabilities. Additionally, the choice between them will depend on the specific requirements of the circuit where they are used.
Can a capacitor store electric energy from a wind mill to discharge into a storage battery?
Yes, but it would not be cost effective. The battery has more "capacity" than a capacitor. Best to simply charge the storage battery directly from the wind mill.
I charged a homemade capacitor with a 9v you touched your tongue to the capacitor and you got no charge?
In order to feel 9V on your tongue, you need enough current, for enough time, for your brain to recognize the current.Homemade capacitors tend to be rather low in capacitance. The resistance of your tongue might then discharge the capacitor rather quickly, and you might not notice the voltage before it goes to zero. Try this with a large capacitor, such as a few hundred microfarads and see what happens. Please do not charge the capacitor to more than 9V - you do not want to hurt yourself!
What is the effect of inserting a dielectric other than air or vacuum between the plates of a capacitors?
Inserting a dielectric material between the plates of a capacitor increases the capacitance of the capacitor. The dielectric reduces the electric field between the plates and allows for more charge to be stored. This results in an increase in the amount of electric potential energy that can be stored in the capacitor.
What is the net charge of a capacitor?
if we apply 1volt through battery to the capecitor than 1 amp current will stored in capecitor
Can a capacitor create more Amps than is put into it at high voltages?
You better believe it, otherwise you're in for a surprise. A capacitor is a current storage device, and even when fed by a small charge from a (say) kV supply, it will eventually acquire the full capacitance charge at the charging voltage.The charge is stored as a distortion of the insulating material, and when it discharges, if into a low-resistance circuit, the current will be high.And with high voltage capacitors, there may be a small hysteresis of the dielectric, and this will relax back to a zero stress position only slowly.So you should discharge an HV capacitor several times, waiting a few seconds between discharges.This is a mistake many technicians make, but generally only the once!
Output voltage of half wave rectifier without capacitor filter is less or more than rectifier with capacitor filter?
less
Which is better for a digital camera with 12 mega pixels a li-ion or ni-mh battery?
For any digital camera a Li ion battery is better than Nimh because it holds more charge and does not lose its charge nearly as fast when the camera is not in use.
Why is the charging time of a capacitor lower than the discharging time?
The charging time of a capacitor is usually lower than the discharging time because during charging, the voltage across the capacitor is increasing from zero to its maximum value, which initially allows a higher current to flow. During discharging, the voltage across the capacitor is decreasing from its maximum value to zero, resulting in a lower current flow. This difference in current flow affects the time it takes for the capacitor to charge and discharge.
Can you use one 555 timer to measure capacitor?
Yes. Setup the 555 as an oscillator and plug the capacitor under test into it and measure the frequency of the signal generated. For more precision, measure the charge time only, and use a constant current source, but that is getting more complicated than need be - there are far better ways to test a capacitor than with a 555.
