text: Simply stated, a capacitor is a device that can store a charge, acting as a sort of short-term battery that can smooth out power fluctuations and perform a variety of other jobs.
text: Dielectric absorption occurs when a capacitor that has remained charged for a long time discharges only incompletely when briefly discharged.
text: If the capacitor can hold more charge for a given voltage drop across it, then its capacitance is higher.
text: Capacitors may retain a charge long after power is removed from a circuit; this charge can cause dangerous or even potentially fatal shocks or damage connected equipment.
text: In particular, a capacitor has a lower energy density and charges and discharges more quickly.
text: When using a rectifier for demodulation the capacitor and load resistance must be carefully matched: too low a capacitance makes the high frequency carrier pass to the output, and too high makes the capacitor just charge and stay charged.
text: Once the engine is warm, the capacitor is fully charged in just 20 seconds and can maintain a charge with the engine off for about 30 minutes.
text: Because the conductors (or plates) are close together, the opposite charges on the conductors attract one another due to their electric fields, allowing the capacitor to store more charge for a given voltage than when the conductors are separated, yielding a larger capacitance.
text: Now, to figure out how much charge a capacitor is currently storing you need this equation:
text: What capacitance is needed to store of charge at a voltage of 120 V?
text: This is because the greater the capacitance, the more charge the capacitor has.
text: Dielectric absorption occurs when a capacitor that has remained charged for a long time retains some charge when briefly discharged.
text: The bigger the plates, the closer they are, and the better the insulator in between them, the more charge a capacitor can store.
text: If you disconnect the power, the capacitor keeps hold of its charge (though it may slowly leak away over time).
text: The voltage at which the capacitor is no longer able to store a charge, breaking down into a short (or nearly short) circuit
text: The voltage at which the capacitor is no longer able to store a charge, breaking down into a short (or nearly short) circuit Tolerance: How close to the given capacitance the capacitor can be expected to stay
text: So the capacitor can store charge.
text: A capacitor is an element which can store charge.
text: What determines how much charge a capacitor can store?
text: Capacitors, as well as other capacitors used for other purposes in circuits, can store charge long after they have been disconnected from the circuit, or after the power was disconnected from the device.
text: Dielectric absorption occurs when a capacitor that has remained charged for a long time retains some charge when briefly discharged.
text: Dielectric absorption occurs when a capacitor that has remained charged for a long time discharges only incompletely when briefly discharged.
text: Dielectric absorption occurs when a capacitor that has remained charged for a long time discharges only incompletely when briefly discharged.
text: C affects the discharging process in that the greater the capacitance, the more charge a capacitor can hold, thus, the longer it takes to discharge, which leads to a greater voltage, V C .
text: C affects the charging process in that the greater the capacitance, the more charge a capacitor can hold, thus, the longer it takes to charge up, which leads to a lesser voltage, V C , as in the same time period for a lesser capacitance.
text: C affects the discharging process in that the greater the capacitance, the more charge a capacitor can hold, thus, the longer it takes to discharge, which leads to a greater voltage, V C .
text: Capacitors may retain a charge long after power is removed from a circuit; this charge can cause dangerous or even potentially fatal shocks or damage connected equipment.
text: How much charge a capacitor can retain and at what voltage is determined by the specifications of the capacitor.
