Can Voltage Be Negative? Understanding Negative Voltage
The concept of negative voltage is sometimes less intuitive than the concept of positive voltage. Perhaps this is because many low-voltage electronic systems do not use negative voltage supplies or because a "negative" voltage implies that a source has a "less than zero" ability to drive current through a circuit. Though many useful and even high-performance …

What Precautions Should Be Taken When Using Capacitors?
When outputting a negative voltage, the negative pole is connected to the output terminal, and the positive pole is grounded. When the polarity of the filter capacitor in the power circuit is reversed, the filtering effect of the capacitor is greatly reduced.
Capacitor Polarity: What You Need to Know
Capacitor polarity is the designation of the positive and negative terminals of a capacitor. This is important because capacitors can only be connected to a circuit in the correct polarity. 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.

OTRA-based positive/negative grounded capacitance multiplier
A positive/negative grounded capacitor multiplier circuit has been proposed using an OTRA, a voltage buffer, three virtually grounded resistors and a capacitor. The proposed CM circuit has been made electronically tunable by replacing the passive resistors with identical MOS transistors operating in the triode region.
Flexi answers
Grounding a capacitor involves connecting one of its terminals to the ground or earth. This is typically done using a wire. The ground serves as a reference point and helps to stabilize the voltage across the capacitor. It also provides a path for the discharge of the stored energy in the capacitor, which can be important for safety reasons.

Ground (electricity)
Long-distance electromagnetic telegraph systems from 1820 onwards [a] used two or more wires to carry the signal and return currents. It was discovered by German scientist C.A. von Steinheil in 1836–1837, that the ground could be used as the return path to complete the circuit, making the return wire unnecessary. [2] Steinheil was not the first to do this, but he was not aware of …
Air Conditioner Capacitors
Two common signs that an AC capacitor is failing or has gone bad are: first, your air conditioner is having a hard time starting up or won''t start at all; it might hum or click instead of kicking on as usual. Second, your AC might start up but struggle to cool your home efficiently, running longer than it should or not blowing cool air.
DC-system grounding: Existing strategies, performance analysis ...
By the occurrence of fault at the positive pole, the voltage of the negative pole jumps to 2 p.u which necessitates the insulation level of full DC voltage for the DC system.
What is Ground in Electronic Circuits?
Up until now, the designer has been calling the negative pole of the battery "ground" when in fact it was unreferenced, or floating. As a result of connecting the system to the house, the positive pole of the battery is now +150VDC and the negative -150VDC, when measured with respect to house ground.
Why to disconnect the negative/ground terminal, not positive?
If one side of a supply is grounded, you switch the other one. If neither side is grounded, you double pole switch both. If it''s a three rail DC supply you''d either switch the two outers (grounded) or all three poles (isolated). Switching goes on the side that will render the circuit beyond the switch safest in the off position.
