You are given a number of 2μfarad capacitors each with a max working potential difference of 10V how would you construct capacitor of 2μfarad capacitance suitable for use upto 20V explain?
As far as potential difference is concerned if they are in series we have to add them. If they are in parallel the potential difference remains the same. So we need two parallel sets to be connected in series. Now as we connect in parallel the effective capacitance would be got by adding the capacitance. If capacitors of equal value are connected in series, then its value will be reduced to half of the individual. So let us construct two in parallel. So effective will be 4 uF but with 10 V Another set of two in parallel has 4 uF with 10 V. Now these two sets are connected in series. Hence the effective would become 2 uF but the voltage will be 10+10 ie 20 V. Hence the problem is solved. So we need two sets in series
Difference between electrolytic and non-electrolytic capacitors?
Electrolytic Capacitors:1. It provides high capacitance in small volume.2. It has got polarity.3. It is not suitable for high frequencies due to losses in dielectrics.4. It is generally available in 1-100 µF rangeNon-Electrolytic Capacitors:1. Its capacitance depends on dielctric constant of the bulk.2. It doesn't have polarity.3. It is widely used at all frequencies.4. It ranges from pico Farads to fractions of µF.
Increasing the capacitance of the coupling capicitor in an RC coupled amplifier has what effect?
the circuit will pass waves of a lower frequency
Why are capacitors required to be in capacitor banks?
Capacitor banks are used to control the power factor in a power system. By connecting suitable capacitors the power factor can be controlled / maintained at a desired level. The requirement of a capacitor changes as the load changes dynamically. The same amount of capacitors can not maintain the desired power factor all the time. To be able to connect only the required number of capacitors, multiple (bank of capacitors) capacitors are included in a system. An automatic controller senses the actual power factor and connects and disconnects the capacitors from the bank as required
Why LC oscillator not suitable for audio frequency?
Another type of sine-wave generator uses inductors and capacitors for its frequency-determining network. This type is known as the LC OSCILLATOR. LC oscillators, which use tank circuits, are commonly used for the higher radio frequencies. They are not suitable for use as extremely low-frequency oscillators because the inductors and capacitors would be large in size, heavy, and costly to manufacture.
Why LC oscillators are not used for low frequency?
They are not suitable for use as extremely low-frequency oscillators because the inductors and capacitors would be large in size, heavy, and costly to manufacture.
Why RC oscillators are not suitable for high frequency generation?
Because an RC oscillator is affected by stray capacitance in the active components in the circuit. HF oscillators use an LC tuned circuit to define the frequency.
The air conditioning work in 230 volt why the compressor use capacitors of 370 and 440 volts if he only need mfd to start?
An AC capacitor is composed of two DC capacitors with the foil ends (-) connected together and the center ends (+) connected to the outside. There are variations to the connections. Each capacitor has to have the voltage rating required by the application -- and there are two capacitors in series in an AC capacitor. A 230V AC capacitor, depending on manufacturing design standard, may not be suitable for starting a 230V air conditioner.

What is electrlytic capacitor?
Every single electrolytic capacitor (e-tops) are energized capacitors whose anode cathode (+) are made of an extraordinary metal on which a protecting oxide layer starts by anodization (shaping), which goes about as the dielectric of the electrolytic capacitor. A non-strong or strong electrolyte which covers the surface of the oxide layer on a basic level serves as the second terminal (cathode) (- ) of the capacitor. The huge capacitance of electrolytic capacitors makes them especially suitable for passing or bypassing low-recurrence signs up to some uber hertz and putting away a lot of vitality. They are generally utilized for decoupling or clamor sifting in force supplies and DC connection circuits for variable-recurrence drives, for couple signs between amplifier stages, and store vitality as in a flashlamp.
What is a potentiometric titration?
A potentiometric titration is one in which the end-point is detected by measuring the change in potential of a suitable electrode during the titration.
