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 else can I help you with?
What is the percentage of charge on a capacitor at the 4 time constant?
At 4 time constants, a capacitor in an RC charging circuit is approximately 98.2% charged. The charging equation shows that after each time constant (τ), the charge on the capacitor increases significantly, approaching its maximum value asymptotically. By the fourth time constant, the capacitor is effectively considered fully charged, with negligible difference in charge compared to the maximum value.
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.
Capacitor not charge?
If a capacitor will not charge, it is open, i.e. damaged.
How much charge is held on one plate of a 15 farad capacitor brought to 6v?
The charge stored on a capacitor can be calculated using the formula ( Q = C \times V ), where ( Q ) is the charge in coulombs, ( C ) is the capacitance in farads, and ( V ) is the voltage in volts. For a 15 farad capacitor charged to 6 volts, the charge is ( Q = 15 , \text{F} \times 6 , \text{V} = 90 , \text{C} ). Therefore, one plate of the capacitor holds 90 coulombs of charge.
What is capacitor function?
The capacitor is used to store the charge applied to it.This stored charge can be used to absorb voltage spikes and voltage drops.AnswerIt's a misconception that a capacitor stores charge. In fact, it stores energy. The net charge on a fully-charged capacitor is the same as on a fully discharged capacitor.
How can you identify that which plate of capacitor is positively charged?
FOR tESTING THE SIGN OF CHARGE ON BODY, a device called GOLD LEAF ELECTROSCOPE. When the disc of a positively charged is touched with any plate of the charge capacitor. IF the divergence of gold leaf increases, then the plate is positively charged and if the divergence in the leaf decrease then the plate of the capacitor is nagatively charged.
What is the net charge on the charged capacitor?
there is no net charge on the capacitor because nomber of positive and negative charge and negetive are equal.
Why does a charged capacitor have a net charge of zero?
A charged capacitor consists of two conductive plates with opposite charges. These charges cancel each other out, resulting in a net charge of zero for the capacitor as a whole.
Does a charged capacitor have an identical level of charge on both plates?
No, in a charged capacitor, one plate has a positive charge and the other plate has a negative charge. The magnitude of the charges on the plates is equal and opposite, resulting in a net charge of zero for the entire capacitor.
When a capacitor is neutralized where does excess charge go back to?
A capacitor is "charged" when the charge on the two plates is not the same. When you neutralize or "discharge" the capacitor you are transferring charge back to the low plate, so that the charge on both plates is the same.
What current exists in a capacitor when it is fully charged in an RC circuit?
When a capacitor is fully charged in an RC circuit, it holds a stored electrical charge. This charge creates an electric field between the capacitor plates, with no current flowing through the circuit at that moment.
What is the percentage of charge on a capacitor at the 4 time constant?
At 4 time constants, a capacitor in an RC charging circuit is approximately 98.2% charged. The charging equation shows that after each time constant (τ), the charge on the capacitor increases significantly, approaching its maximum value asymptotically. By the fourth time constant, the capacitor is effectively considered fully charged, with negligible difference in charge compared to the maximum value.
What happens when a charged capacitor is connected across an uncharged one?
When a charged capacitor is connected to an uncharged capacitor charge flows from the charged to the uncharged capacitor until there is no net force on the charge carriers. This means that both capacitors are at the same potential, because if they were not, there would be an electric fieldand hence a force on the charge carriers of magnitudeand the charge carriers would move to equalize the potentials and reduce the electric field and hence the force, eventually to zero. Of course, as charge flows from one capacitor to the other, the total charge is conserved. In the diagram above, when switch is closed chraged flows from the top capacitor to the bottom. When charge has stopped flowing, Also, because the potentials are equal(1) Suppose then that the capacitor at top left is initially charged to potential ofand that it has capacitanceand is then connected to a capacitance Initiallystores a charge Then (3) From (1) (4) Sub (4) into (1) to get Now usefor either capacitor to findUsing it for (2) gives from A Level Physics Notes
What does a capacitor charge graph illustrate about the behavior of a capacitor in an electrical circuit?
A capacitor charge graph shows how the voltage across a capacitor changes over time when it is connected in an electrical circuit. It illustrates that initially, the voltage across the capacitor rises quickly as it charges up, but eventually levels off as the capacitor becomes fully charged. This graph helps to understand the time it takes for a capacitor to charge and how it behaves in a circuit.
What happens to the capacitance fi the charge on the plates of a capacitor is doubled?
The capacitance doesn't depend on the charge stored in it. The capacitor has the same capacitance whether it's charged by a DC and just holding it, or in an AC circuit where the charge on it keeps changing and reversing, or in a box on the shelf connected to nothing and not charged at all.

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.
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
