What do non Electrolytic capacitor do?
first lets explain what an electrolytic capacitor is to identify an electrolytic capacitor look for positive and negative indicators (non aren't polarized). the reason that its polarized is because the anode is normal but the cathode is a normal one with electrolyte soaked paper this allows more electrons to be stored thus more energy. a non can only hold what the metal can take. but if you reverse the flow it heats and the steam causes the canister to blow. basically a non electrolytic capacitor is a capacitor with no extra features, just a couple of aluminum plates separated by air.
Does a capacitor block ac current dc current or both?
No you can't use DC capacitors in Ac because in DC current , the current flows directly while in AC current, the current flows curved zig-zag. Thus Dc equipment can't mingle with AC as they need Direct flow. So DC capacitors can't be used for AC current...................AnswerMost capacitors will operate on either DC or AC. The exception is the polarised-type capacitor, which is designed to operate with a DC or an appropriately-biased supply.Often, a capacitor's rated voltages is specified in terms of DC -for example, '100 V (DC)', so care must be exercised if it is to be used with AC. This is because we always measure AC voltages as root-mean-square (rms) values, not as peak values. For example, '100 V (AC)' actually peaks at 141 V*. So, applying 100 V (AC) to a capacitor rated at 100 V (DC) may cause its dielectric to fail. In this example, the maximum allowable AC voltage must be 70.7 V, which peaks at 100 V.(*To explain: Vrms = 0.707 Vmax )
Explain the Potential across the resistor during the charging and discharging process of the capacitor?
The voltage across a capacitors given as a time constant t= 63% the resistor value multiply buy capacitor value. it doesn't matter if it goes more or less negative it will follow this function
Explain capacitance of bundled conductor line?
Capacitors are formed by placing two conductors near each other. Usually, they are plates separated by an insulating dielectric. The capacitance is a function of the area and closeness of the plates. Bundled conductors have capacitance for the same reason - they are conductors close to each other. Since capacitors work by transferring charge (remember that the equation of a capacitor is dv/dt = i/c) then a signal on one conductor can induce a "copy" of the signal on the other line - usually a faint copy, but a copy nontheless. This induced voltage effect is also known as interference, and must be considered in the final system design.
Explain the function of the capacitor and inductor in a power supply?
A capacitor resists a change in voltage (dv/dt = i/c). An inductor resists a change in current (dl/dt = vl). Together, a capacitor and inductor make a tuned circuit. Usually, in a linear power supply, there is a capacitor in parallel with an inductor in series, and often, in a pi filter, another capacitor in parallel. This reduces the peak to peak voltage at the output. It is also possible to put an inductor in series with the rectifier diode, as as to reduce inrush current. In a switching power supply, things are a little bit different. The primary inductor is a current pump, maintaining constant current flow to the load, controlled by the pulse-width oscillator which switches between on-current from source and off-current from schottky diode. The capacitor in this case filters the output, so as to reduce high frequency harmonics.

How would you explain electrolytic refining?
The process of purifying metal ingots which are suspended as anodes in an electrolytic bath, alternated with refined sheets of the same metal, which act as cathodes.
Could anybody please explain how exactly high pass and low pass filters work?
Filters are composed of capacitors and inductors. These component "react" differently to different frequencies. If you modulated the voltage frequency to a series capacitor, it would start out looking like a very big resistance, which would become incrementally smaller as the frequency is increased. Inductors act in the exact opposite fashion. A simple lowpass filter is compossed of a resistance and capacitor in series, with the output across the capacitor. Using a voltage divider: Voutput = Vinput * (resistance of cap) / (resistance of cap + R) A simple highpass filter is composed the same, with the output across the resistor. This type of filter is a first order filter, because there is one inductor or capacitor. Adding more of these elements will cause rippling in the frequency response, and can cause the rolloff / decay to occur faster. Putting two capacitors in series or parallel "looks" like one element, so for a second order filter you must use a cap and an inductor. For a third order, you must use two of one and one of the other "in between" them - for example have the input to a capacitor, where the other side is tied to the inductor and other capacitor; the inductor's other terminal is connected to ground, and the output is from the other capacitors second terminal.

You need to explain what you mean by '4 mb'.

Does capacitance exist between two thin current-carrying conductors Explain?
The conductors of the transmission line act as a parallel plate of the capacitor and the air is just like the dielectric medium between them.A capacitor is a device used to store electrical charge and electrical energy.
