Charging and discharging of a capacitor. Experimental data. Example e-ProLab file of the capacitor charging.
It is important to study what happens while a capacitor is charging and discharging. It is the ability to control and predict the rate at which a capacitor charges and discharges that makes capacitors really useful in electronic timing circuits. When a voltage is placed across the capacitor the potential cannot rise to the applied value instantaneously. As the charge on the terminals builds up to its final value it tends to repel the addition of further charge. The rate at which a capacitor can be charged or discharged depends on: a the capacitance of the capacitor and b the resistance of the circuit through which it is being charged or is discharging. This fact makes the capacitor a very useful if not vital component in the timing circuits of many devices from clocks to computers.

Large-value capacitors are required for this experiment to produce time constants slow enough to track with a voltmeter and stopwatch. One terminal of each capacitor should be marked with a definite polarity sign. Usually, capacitors of the size specified to have a negative - marking or series of negative markings pointing toward the negative terminal. Failure to heed proper polarity will almost surely result in capacitor failure, even with a source voltage as low as 6 volts. When electrolytic capacitors fail, they typically explode , spewing caustic chemicals and emitting foul odors.
Lab 4 - Charge and Discharge of a Capacitor Introduction Capacitors are devices that can store electric charge and energy. Capacitors have several uses, such as filters in DC power supplies and as energy storage banks for pulsed lasers. Plasma physics makes use of the energy storing ability of capacitors. In plasma physics short pulses of energy at extremely high voltages and currents are frequently needed. A capacitor can be slowly charged to the necessary voltage and then discharged quickly to provide the energy needed. It is even possible to charge several capacitors to a certain voltage and then discharge them in such a way as to get more voltage but not more energy out of the system than was put in.
Тот даже не повернул головы и выключил двигатель. - Двадцать тысяч! - крикнул Беккер. - Мне срочно нужно в аэропорт. Наконец парень посмотрел на. - Scusi? - Он оказался итальянцем.
Нуматака терпеть не мог вести дела подобным образом, он ненавидел, когда хозяином положения был кто-то. С самого начала его преследовала мысль, что звонки Северной Дакоты - это западня, попытка японских конкурентов выставить его дураком. Теперь его снова одолевали те же подозрения. Нуматака решил, что ему необходима дополнительная информация.
