Make sure you're using a non polarized electrolytic capacitor, otherwise it isn't going to work well.
I'm not sure, but I would say you should be able to apply the same RMS AC as it is rated for DC:
AC Peak - Peak = RMS AC / (2*sqrt(2))

What does an electrolytic capacitor do?
Electrolytic capacitor are used in dc power supplies to filter ac ripple . The rectifier turns ac in to pulsating dc and with a capacitor across the output it holds a charge and so pulsating dc never goes down to zero.. Salunke pratik sigma institute of engineering .vadodara
Which type of coupling capacitor is used in RC coupling?
Capacitor coupling involves the use of coupling capacitors.Coupling capacitors are mostly ceramic capacitors.These are in the range of 0.47picofarad to 4.7 microfarad.Never use an electrolytic capacitor for coupling.It is meant for bypassing.coupling capacitors aloow AC and block DC components of a DC coupled signal.This DC component may also include noise,a grounded voltage signal or a step function.The analysis of the circuit involves determining the h-parameters of the amplifying stages,the Fourier transform of the signal applied and at various points of the circuit and the Laplace transform of the circuit sections in order to know the conditions of operations .Using complex engineering mathematics,the time varying analysis can be performed .This makes use of the Maxwell's equations to know the fields of the passive and active elements.
How does the positive clamper works in electronic circuits?
A negative clamper circuit is considered. It shifts original input signal in a downward direction.While positive input is applied, diode is forward biased. The output voltage is Vo which is equal barrier potential of the diode. The capacitor is charged to V-Vo.When negative input cycle, diode does not conduct because it is reverse biased and the capacitor can not discharge very much because time constant (RC) choosen is high. Now output is sum of input voltage and capacitor voltage and it is equal to -(2V - Vo). Now peak to peak output voltage is difference of output voltages when positive and negative half cycles and it is equal to V-(-(2V - Vo)) or 2V.In negative clamper, input signal is pushed downward and positive peak of the output signal coincides with zero level.In positive clamper circuit, unlike in negative clamper circuit, diode is connected reversely.There is no change in connection of capacitor. But resistor is connected after diode. Positive clamping circuit shifts a input signal in upward direction. The output of this circuit shows that negative peak of signal coincides with zero level.
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.
Capacitor can not work in DC signal?
For dc voltage signals, a capacitor is an open circuit. Current flow into a capacitor is proportional to variation of voltage (I = C dV/dt). So, if you polarize a capacitor with constant voltage, there won't be current flow. Instead, if you impose constant current, capacitor voltage will grow linearly (as a proof, you can integrate V-I formula with respect to time). An analogy can be found with hydraulics: current is water carrying capacity, voltage is water height (relate to potential energy) and capacitor is like a lung (i'm not sure about this term, it's a sort of elastic balloon full of water that squeezes and provides water when pressure falls down; when pressure comes up again, it recharges itself: it acts as water pressure stabilizer).
How does a capacitor allow ac?
A capacitor allows AC (to pass through) because capacitors resist a change in voltage. The equation of a capacitor is ... dv/dt = i/c ... meaning that the rate of change of voltage in volts per second is equal to current in amperes divided by capacitance in farads. The simplified explanation (using more words) is that, when a DC voltage is applied to a capacitor, it ultimately charges to that DC voltage and, at equilibirum, presents a large impedance, but when an AC voltage or step change is applied to a capacitor, it initially presents a low impedance, allowing the AC or step to pass through. If you have an AC signal riding on top of DC, the capacitor will stabilize to an output DC offset of zero while passing the AC. This is useful, for instance, when coupling an AC signal to the input of a transistor amplifier, while allowing the base bias circuit to keep the transistor in its intended bias state, while at the same time allowing the AC signal to pass through into the transistor and be amplified.
What is capacitor smoothing?
A Smoothing Capacitor is a capacitor which helps to smooth out fluctuations that may exist on a power supply line.
What is edge speed in electronics?
A voltage is applied to a signal line. The voltage of the line changes gradually from 0 to +V. The "edge speed" is the rate of change of voltage of the line. A voltage is applied to a signal line. The voltage of the line changes gradually from 0 to +V. The "edge speed" is the rate of change of voltage of the line.
What is the role of a capacitor at the non-inverting input of an op-amp?
The capacitor blocks the DC portion of the signal and therefore only the AC portion is amplified. i.e if the signal applied exists at a 2 Volt level for instance, after the capacitor the 2 Volts will be trimmed off.

What is envelope detection?
When an AM signal is received, the receiver must perform a converse process to get the original signal ( Information Signal ) back . This process is known as detection or demodulation, the simplest process which is used widely in AM radios is the Envelop Detector . Envelop Detector is an electronic circuit which is used to recover ( Demodulate ) the original signal in AM systems, its constructed from just one diode, one capacitor and one resistor . This is essentially just a halfwave rectifier which charges a capacitor to a voltage = the peak voltage of the AM signal . However .. the output of the detector follows the envelop of the modulated signal. On the positive cycles of the input signal, the diode conducts and the capacitor charges up to the peak voltage of the input signal. As the input falls below this peak value, the diode is cut off, because the capacitor voltage is greater than the input signal voltage, thus causing the diode to open. The capacitor now discharges through the resistor at slow rate . The discharge process continues until the nest positive half-cycle. When the input signal becomes greater than the output across the capacitor, the diode conducts again and the process is repeated .
Can you change 680 microfarad capacitor with 1000 microfarad at 35 volts?
Yes you can - in principle, and in many cases. As long as the form factor of the new capacitor is the same as the form factor of the former capacitor, and as long as the maximum voltage of the new capacitor is higher than the max voltage of the former capacitor, you can often replace a lower-rated with a higher rated capacitor. However... Apart from the nominal capacity and maximum voltage rating, you should also consider the capacitor's design. There are many ways to make a capacitor, from tiny ceramics over various plastics and metal foil combinations to electrolytic capacitors. Apart from the capacity and voltage rating, the different types of capacitors also vary in a lot of other aspects: impedance, precision, drift with time and drift with temperature, are just some. Electronics designers typically choose the capacitors carefully, and considering all those aspects. Only when those aspects don't matter much, designers tend to chose the cheapest technology. In such a case, you're safe to replace. In most cases of capacitors rated at 1 micro Farad and above, electrolytic capacitors are used (typically small cylinders). Those are typically selected because they offer excellent value (capacitance) for money, and you're typically safe to replace them, subject to above rules. CAUTION: some capacitors have a distinct polarity. You must make sure to observe the polatiry when replacing polarized capazitors. Failure to do so can result in serious harm (basically, the part might explode).
What is the function of electrolytic cell?
Electrolytic capacitors are used for power filter, decoupling, signal coupling and time constant setting, DC blocking, etc. Polarized electrolytic capacitors usually play a role in power supply circuits or intermediate frequency and low frequency circuits for power supply filtering, decoupling, signal coupling, time constant setting, and DC blocking. Generally electrolytic capacitors cannot be used in AC power circuits. When used as filter capacitors in DC power circuits, its anode (positive) should be connected to the positive terminal of the power supply voltage, and the cathode (negative) should be connected to the negative terminal of the power supply voltage.

If the voltage applied across a capacitance is triangular in waveform then the waveform of the current?
Depend the value of capacitor. Capacitance in series act like a high pass filter, while in parallel act like low pass filter. By fourier series, triangular wave is combine of series of the sine or cosine waves. Therefore by certain capacitance, sine wave can preduce by applied a triangular signal through a capacitor. Current is just 90 degree shift from voltage, shape is same.
Why don't capacitors allow DC current to pass?
