What is the function of capacitor in full wave rectifier with smoothing capacitor circuit?
is a device that smoothen your half-wave rectification into a full-wave rectification after using a 4 diode and 1 resistor , after adding a capacitor , there will be a almost steady output , it charges the capacitor when is forward biased which is the first half wave , and discharge when is reverse biased to stablelize the wave into a almost same potential difference compare to a.c
What is the purpose of the capacitors at the input and output signals?
There are two primary uses of a capacitor in the biasing of a transistor. One is to isolate the DC component of the input or output signal from the input or output of the transistor. This is often done in audio applications where the input signal is centered around ground reference, but the base is biased at 0.7 volts. Similarly, the collector is biased away from ground, but the signal needs to be shifted back to ground reference. The second is to change the gain as a function of frequency. Depending on where the capacitor is located in the circuit, the capacitative reactance as a function of frequency can add to or subtract from the bias point and/or gain of the circuit. Usually, this capacitor would be located on output side, along with the emitter or collector resistors.
What is a feed through capacitor?
A feed through capacitor is a type of capacitor (if you don't know how a capacitor works, look this up before going on) for bypassing RF voltage frequencies to ground of a transmitters chassis. It is built by putting a dielectric around a conductor and encasing it in a metallic tube.. so that the conductor is one plate and the outer tube is the second plate. They are shown in a schematic diagram by a straight line and a half moon to the side much like standard capacitor with the exceptions there are three connections. Two for the conductor plate and usually one for the outer shield. The higher frequencies that travel down the conductor plate 'pass through' (no current flows through the dielectric of a capacitor, unless it is leakage current or breakdown current) the dielectric to the outer case (typically grounded), while the lower frequencies (and DC) continue on through the conductor. So, in effect, what a bypass capacitor does is pass the DC current through it while bypassing the AC to ground of the chassis. The value of the capacitor will determine the capacitive reactance and what frequencies will pass more freely to ground.
What is run capacitor in single phase motor starter with three wire?
A run capacitor and a starter capacitor are not the same thing. A run capacitor is energized the entire time the motor is running, and a start capacitor is not. A run capacitor is one that changes the current on the windings of a single phase AC induction motor to create a rotating magnetic field to energize a second-phase winding. A start capacitor increases starting torque, allowing a motor to be turned on rapidly. It stays in the circuit only long enough to bring the motor to 3/4 of full speed. Some motors then continue to run with a run capacitor.
Is it OK to use an unpolarised capacitor in a circuit where there was originally a polarised one?
Well... Maybe yes, maybe no. It depends on two things. First, the physical size of the non-polarized capacitor may well be larger than the original size of the polarized capacitor, so it might not fit. Second, you have to consider the RMS current rating of the capacitor. Often, a polarized capacitor, such as an electrolytic capacitor, is intended to be used in a power supply, and is rated for a certain RMS current. A non-polarized capacitor, however, might not be rated for the same or higher RMS current, so it would not be able to handle the load.
Why you use capacitor in transistor amplifier in output?
The capacitor is used to block DC bias from the output, so that only the AC signal is passed. In an audio amplifier, for instance, unwanted DC in the output would cause distortion when fed to a speaker, or could even damage the speaker or amplifier. In the case of interstage capacitors, they block DC so that the output of the first stage does not affect the bias of the second stage.
How do you bypass the conlog immobilizer on your automatic corsa?
you have a black box when you trace the wires back when you get to the box on the left will be four black connectors disconnect them then loop the first two then the second two and disconnect the rest and away you go

How fast can a battery charge a discharged capacitor in the absence of a resistor?
Depends on the size of the battery and the capacitor. If both are small enough to fit in your hand, then some fraction of a second.
What are the output devices of second generation computer?
The devices which gives/show output data of a computer are called "Out put devices".For example Monitor,Speaker and Printer.
Why do you connect a capacitor with an Ac motor?
The capacitor is used to create a second phase from the single phase power source and it is the interaction between these two phases that causes the motor to turn.
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.
Can you break a three phase from a disconnect?
If you mean can you splice in a second circuit from the load side of a three phase disconnect then the answer is no.
Why do you connect a diode in parallel to a capacitor?
1. bec the capacitor not allow the current to pass through it after it has charged & it charged in no time ex:(10^-4 second). 2. because it is necessary to avoid wrong polarity by shorting the terminals of the capacitor and tripping the fuse.
