What is the potential of the positive side of capacitor B?
The potential of the positive side for the capacitor B is always zero, because it is connected to the earth. By clicking “Post Your Answer”, you agree to our terms of service and acknowledge you have read our privacy policy. Not the answer you're looking for?
Is a capacitor a ground terminal?
The capacitor is for EMI filtering, it is there to reduce common mode noise. Yes they are ground terminals. One is the ground reference for unisolated mains input side, the other one is the ground reference for isolated low voltage output side. Therefore it must be of special type for safety reasons, the type is called an Y capacitor.
What is the difference between a voltage source and a capacitor?
The only difference would be that the positive terminal of the voltage source in circuit B would be referenced to ground. Whereas the voltage source in circuit A would be 'floating'. The potential of the positive side for the capacitor B is always zero, because it is connected to the earth.
What is the difference between polar and tantalum capacitors?
One important difference in polar capacitors is that electrolytic caps have the negative terminal marked, and tantalum caps mark the positive. Always be sure of the relative voltage differences of points with a capacitor between them so the smoke stays in the device.
Do electrolitc capacitors have a minus - connection?
Electrolitc capacitors have markings for the minus (- connection) most times there is a coloured band on that side. You should take care that the polarity of the electrolitic capacitors is correct, otherwise you can damage the capacitor (sometimes even with a loud bang). I have Bertus, but it still does not answer my most basic question.
Why is y capacitor a special type?
One is the ground reference for unisolated mains input side, the other one is the ground reference for isolated low voltage output side. Therefore it must be of special type for safety reasons, the type is called an Y capacitor. Your Answer
filter
The capacitors to ground form a low-pass filter for the lines they''re connected to, as they remove high-frequency signals from the line by giving those signals a low-impedance path to GND. See this question.

Ensure a secure connection, either by soldering or using a wire connector. Connect …
electrostatics
It is the potential difference across the plates that determines the charge--not the potential relative to infinity. Connecting the positive plate to ground will not cause a current (dQ/dt) to flow since it does not effect to potential difference. The final voltage across the capacitors would be the same. So the final charges would be the same.

Faults in DC Networks
Pole-to-ground, as the name suggests, is the short-circuit between the pole (positive or negative) and the ground. This type of fault most commonly occurs in dc cable; for example, the aging of insulation in cable can cause the conductor getting in contact with the ground. The system earthing configuration determines the formation of fault current loop. …
Do Capacitors Have Polarity – How Will You Tell?
Polarized tantalum capacitors have negative and positive poles. Its designation is also a surface mount to fit on a circuit board, and it has a yellow color. (tantalum capacitors) Furthermore, one of its marked ends (in-dash) indicates the positive pole, making the other end a negative pole. Radial electrolytic capacitors'' polarity . A radial electrolytic capacitor cover has …

Capacitor Polarity: What You Need to Know
If a capacitor is connected in the wrong polarity, it can be damaged or even explode. There are two main types of capacitors: polarized and non-polarized. Polarized capacitors have a positive and negative terminal, and must be …
Is it healthier for a capacitor to be discharged to itself or to "ground…
The only GUARANTEED safe answer is to discharge the capacitor, through a suitable resistor, across the capacitor terminals.. It is true that in most cases one side of the capacitor will be grounded and the other attached to some rail, HOWEVER this is NOT TRUE in all designs. There is no guarantee that grounding either pin of the capacitor to frame ground …
Grounds Power, either postive or negative
How you fix this is to connect shunt bypass capacitors at each power connection and ground. See the figure below. Take note that the capacitors are polarized. The plus terminal must be connected to the higher potential. These capacitors are usually made from tantalum and are ideal for noise bypass situations.
"Ground" vs. "Earth" vs. common vs. negative terminal
I''ve seen very old radios with PNP transistors, and a negative main supply with "positive ground." The positive battery terminal is the Circuit Common. All the measurements in that schematic were negative voltages. Besides 1950s transistor radios, the same thing happens in old VW Beetles, and in some motorbikes. In these, the positive battery terminal is connected …
Capacitor Charging and Discharging when connected …
The net charge of any of those internally connected pairs of plates is always zero. That is, when you charge the capacitors, charge doesn''t leave the wire between C and D, it only moves along it, and is held in place by the electric field of the …
Positive of polarized capacitor connected to ground
I''m trying to make this circuit from here but I''m confused as the positive terminal of polarized capacitors is grounded. Can this be correct? I see a couple other strange things on this circuit. T1 has an open emitter, and T2 appears to be "upside down." And what is the point of C2? Where did you find the circuit? Do you have the BOM?

Understanding Capacitor Polarity: A Crucial Concept in Electronics …
Capacitor polarity refers to the orientation of positive and negative terminals in a capacitor. In polarized capacitors, the positive terminal (anode) and the negative terminal (cathode) must be connected correctly to ensure proper functioning. Conversely, non-polarized capacitors don''t have this restriction and can be connected in any direction. Understanding …

Is GND Positive or Negative
In many power supply configurations, the negative terminal is connected to ground, making it a common practice to consider GND as the negative pole of the power supply. Symbolic Representation: In circuit diagrams, the ground symbol is often used to represent GND, and it''s typically connected to the negative side of the power supply.
