Which type of current capacitor can block and which type of current capacitor can store?
In an electronic circuit a capacitor can be used to block direct current. In general a capacitor stores electric charge. The charge in a capacitor is the voltage times the capacitance and that is also equal to the charging current times the time (all quantities in SI units - seconds, volts, amps, coulombs, farads)
What is the allowable capacitance and voltage difference when replacing a capacitor?
I depends on the application for a rate amplifier the exact value is mandatory but for filtering that can vary greatly since every cap of that type has a very large -/+ tolerance YOU may install a greater voltage breakdown but never a less then the original
What is the work of capacitor in sodium vapour lamp?
A sodium vapour lamp does not include a capacitor in its construction. Any capacitor associated with this type of fixture will be found where the ballast is located and not in the lamp itself.
What is step voltage?
Step voltage is a type of AC voltage where the voltage signal represents a flat step up and then a flat step down.
Which type of voltage is 230 volt?
The classification of 230 volts is in the low voltage range.
Which type of capacitor has the highest voltage rating?
Those with vacuum as the dielectric have.
What type of rotor is used in a capacitor-start motor?
Types of MotorsThere are different types of Capacitor-start motors designed and used in various fields. They are as follows:Single-voltage, externally reversible type,Single-voltage, non-reversible type,Single-voltage reversible and with thermostat type,Single-voltage, non-reversible with magnetic switch type,Two-voltage, non-reversible type,Two-voltage, reversible type,Single-voltage, three-lead reversible type,Single-voltage, instantly-reversible type,Two speed type, andTwo-speed with two-capacitor type.These motors can be used for various purposes depending upon the need of the user. The starting, speed/torque characteristics of each of the above motors can be analyzed before employing them in work.

Which type of circurt does current flow threw each part of and voltage drops along the way?
I believe you are describing a series circuit. One total current flows through each component, and each component has an associated voltage drop. When all the voltage drops are added together, they should equal the source voltage.
Characteristics of relaxation oscillator?
A "Relaxation Oscillator" is an "R/C" oscillator, in which a Capacitor is charged from a DC (Direct Current) fixed voltage source, through a resistor. Connected across this Capacitor is a "device" that, initially, does NOT conduct any current. But when the Voltage on the Capacitor reaches a certain value (depending upon the characteristics of the "device") the "device" will "break down" or "avalanche", or suddenly drastically decrease in resistance. This causes the "device" to quickly start to discharge the Capacitor. However, when the Voltage across the Capacitor and its parallel connected "device' decreases with the discharge cycle, the "device" will suddenly return to its "non-conducting" state, and the Capacitor again begins to re-charge. The Capacitor again reaches the "break down" voltage of the "device", and the process continues, thus effectively creating "oscillations". One version of this circuit uses a simple Neon lamp (such as a NE-1) as the "device". Typically, the "break down" or "ignition" voltage of a neon lamp is around 70 volts. At this point, the gas in the lamp "ionizes", becoming highly conductive. However, when this voltage drops (as the lamp discharges the Capacitor) to about 50-60 volts, the lamp "goes out" (the neon gas is no longer ionized or conducting), and the Capacitor again starts to charge through the resistor. This form of the "Relaxation Oscillator" will not operate at high frequencies (such as Radio Frequencies), and was often used to just generate a "flashing light" (the Neon lamp). With the advent of semiconductors, a device called the Unijunction Transistor (UJT) was developed. It contained three leads, the Emitter, Base 1, and Base 2. The junction of the Resistor and Capacitor is connected to the Emitter, with the "bottom" of the Capacitor (and the negative side of the Voltage Source) connected to Base 1 Base 2 is connected to the positive side of the Voltage Source. Again, when the voltage on the Capacitor reaches the "break down" level, the UJT's "resistance" between the Emitter and Base 1 drastically drops, discharging the capacitor. However, when the discharging current through the UJT drops below a certain level, it again develops a high resistance between its Base 1 and the Emitter, and re-charging of the Capacitor begins again. UJT circuits can operate at higher frequencies than the Neon bulb circuit. Often a resistor is inserted between Base1 and the common or negative side of the voltage source, and the resulting discharge current produced voltage across this resistor is used to trigger other devices. Also, the voltage waveform across the Capacitor approaches a linear "sawtooth" waveform (depending on circuit component values), but not nearly as linear as other approaches. "Devices" of this type are considered to have a "negative resistance" characteristic, which is another discussion in itself.
What type of capacitors polarity of the applied voltage must be taken care off?
Electrolytic capacitors are the type of capacitor that has to have its polarity checked when added into a circuit.See related links below.
What will happen if DC supply is given to the transfomer?
A capacitor resists a change in voltage. Initially, a capacitor given a DC voltage will appear to have very low resistance, but as current flows and time goes by, the resistance will increase as the voltage approaches the applied voltage. At equilibrium, the voltage across the capacitor will be equal to the applied voltage, the current will be zero, and the resistance will be infinity.
Capacitor of 30 pF is expensive?
it will of Rs.340 & $51This depends on on the capacitor voltage and type needed. small signal 30pF capacitors are very cheap (a few cents); a starter cap. for a car, on the other hand, can be quite a bit more expensive.
Describe the functions of the contacts on the top of the capacitor?
If there are only two contacts they are there to allow the capacitor to be connected into a circuit. If this is not a "just for fun" nonsense question, please describe the actual capacitor clearly and it may then be possible to give an answer. Please state: * the capacitance value (it is usually printed on the body of the capacitor) * the working voltage (if it is printed on the body of the capacitor) * the type of body (metal, plastic, etc) * the maker's name (if you know it - it may be shown on the body) * exactly how many contacts there are and where each contact is positioned
Why inductor use in series capacitor in parallel?
That depends on the type of circuit you are talking about. Sometimes both an inductor and capacitor are both in parallel with each other. This is called a tank circuit. Sometimes they are both used in series. These are both examples of resonant circuits. Sometimes the inductor can be in parallel with an applied voltage and the capacitor in series. This is a form of high pass filter. On the other hand, the inductor can be in series and the capacitor in parallel to for a low pass filter.
How a capacitor store charge?
by using capacitor plates. The length,area ,thickness and type of the plate determines the amount of charge a capacitor can store.
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).
