Why doesn't l c circuit simply stop oscillating even when the capacitor has been completely discharged?

Because real inductors, as well as the wires used to connect them to the
capacitors and to the excitation, have some resistance, and where there is
resistance, there is dissipation of energy.

Is capacitor a part of integrated circuit?
A small capacitor can be part of an integrated circuit.
What is the summary for 555 timer?
an oscillating RC circuit
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.
Why the oil filled capacitor is used in permanent split capacitor motor?
An oil filled capacitor is used in (PSC) motor because the capacitor is in the circuit the whole time the machine is running. The capacitor is oil filled to cool it due to being in circuit the whole time
Why capacitor behave as open circuit against alternating current?
Capacitors store electrical charge. Imagine we have a capacitor. At time 0 seconds we connect a DC voltage across the capacitor - immediately as the voltage is connected the capacitor is at 0 volts and the maximum current (relative to the circuit resistance) flows. At this extreme the capacitor can be treated as a short circuit, so for high frequency AC volts we should treat a capacitor as being a short circuit. As time passes the current in the circuit will go down and the voltage of the capacitor will go up - this is because as the capacitor gains more charge it gains more voltage, lowering the voltage across any resistance in the circuit consequently lowering the current in the circuit. When the capacitor is virtually full no current will flow at all and the voltage across the capacitor will equal the DC source voltage. At this extreme the capacitor can be treated as an open circuit, so for low frequency AC (allowing the capacitor to fill up before the current alternates) we can treat the capacitor as being an open circuit. Technically, it is not an open/closed circuit when it comes to AC because the capacitance will results in a signal lag or lead. However, if the frequency is low/high enough the lag/lead is often negligable.
Why do the interior lights stay on when mydoors are shut in my 91 Toyota 4Runner?
The interior lights will remain on for a duration of time after the doors are shut as a safety/courtesy feature. The reason they remain on is the capacitor in the lighting electrical circuitry. The capacitor passes on energy when the circuit is powered, and retains voltage when the circuit is powered down. Once the circuit is powered down, i.e. the vehicle shut off and doors closed, the capacitor still holds that charged voltage and discharges itself over a period of time, usually 30 seconds or so. As it discharges, the electricity moves through the circuit and through the bulbs until the capacitor is completely discharged. Hope this helps!
What is a rectifier with a single capacitor filter suitable to supply?
A circuit that doesn't require a lot of filtering such as a charging circuit for a battery. In a single capacitor filter, the sine wave or AC doesn't get completely eliminated.
Is capacitor a part of integrated circuit?
A small capacitor can be part of an integrated circuit.
How long will it take a 1 μF capacitor to completely discharge through a 47 kΩ resistor?
forever. the discharge curve of an RC circuit is exponential and the closer it gets to discharged the slower it discharges. this is true for all values of capacitors and resistors.
What what is an oscillator?
a circuit that produces a continuously oscillating signal.
What is the summary for 555 timer?
an oscillating RC circuit
What employs a parallel after discharge circuit to produce sustained muscle contraction?
a oscillating circuit
How does an RC work?
The resistor allows a slow charge to enter the capacitor. When this charge reaches a certain point the circuit activates and forces the capacitor to discharge. Once discharged the circuit reverses itself and starts the charge over again. The larger the cap and/or resistor the lower the frequency because it takes longer to charge the cap.
What happens to the current in a circuit as a capacitor charges?
What happens to the current in a circuit as a capacitor charges depends on the circuit. As a capacitor charges, the voltage drop across it increases. In a typical circuit with a constant voltage source and a resistor charging the capacitor, then the current in the circuit will decrease logarithmically over time as the capacitor charges, with the end result that the current is zero, and the voltage across the capacitor is the same as the voltage source.
Effect of shorting out the capacitor in a clamping circuit?
Any circuit using a capacitor will not work if the cap is short-circuited.
How one can know that what kind of capacitor to use in circuit?
paper capacitor
What to expect if a resistor is placed in a dc circuit with a capacitor?
when we replace the resistor with a capacitor ,the current will flow until the capacitor charge when capacitor will fully charged there is no current through the circuit because now capacitor will act like an open circuit. for more info plz E-mailt me at "zaib.zafar@yahoo.com"
