Staying Well Grounded | Analog Devices
The star point need not look like a star—it may be a point on a ground plane—but the key feature of the star ground system is that all voltages are measured with respect to a particular point in the ground network, not just to an undefined "ground" (wherever one can clip a probe). ... all the fast-edge digital currents of the converter ...
Capacitors in a Circuit
Disconnect the wire represented by the red dotted line between the capacitor and R1. Push the button to charge the capacitor. Set your multimeter to the proper voltage range. Put the red probe to the positive side of the cap, and the black to the ground. Record the voltage that first appears. The capacitor will slowly leak through the multimeter.

Crystal Capacitor or not
Now I always learned that crystals need capacitors, ceramic resonators do not. However, one of the things I look at if it needs it or not, is wether or not the crystal/resonator needs to be connected to ground, as I figured the ground is only needed for internal capacitors.

Apparently it failed a few times untill a capacitor/resistor was added between the USB shield and ground, and a small metal tab was introduced to add better contact between PCB ground and the metal case. This then apparently allowed it to pass. ... However (I can add this to the question if need be) I replaced the capacitor and resistor with a ...
Why is there a capacitor between chassis ground and signal
This is likely a stuff option to be able to configure the board to pass EMI radiation standards, for example USA FCC Class B. Generally having earth ground connected to digital ground is a good thing, but if there is a lot of noise on the board, this could cause high frequency analog or digital switching noise, etc, to travel onto the chassis or down the earth ground wire and cause …

It seems all those capacitors are on 5v, look what it says on them, if it says 6.3v or 10v, then 100 percent they''re filtering 5v. Having so many go bad can be a sign that the power supply has started to fail and outputs a bad quality 5v voltage - …
capacitor ground or not?
I have some questions about capacitors (which are very new to me). My question is since they have got +/- sides, do I need to ground them or does this work on hot side only like the image, say the bulb in the image is car park lights. As far as I know, this should take about 1.5 sec to reach 12V.
Mounting Hole Connected to Ground Through Capacitor
The board''s ground plane layer (which serves as the digital/analog/power ground) connects to the DC negative return. The power supply itself has a terminal for a chassis ground connection, which is connected to the one-point system ground. The +/-DC supply, however, is isolated from this chassis ground. $endgroup$ –

Thanks!
Capacitors connected GND to GND
Hi, It''s just to get rid of any static charges, when the board is inserted into the chassis. This is because the edge is going to be the first bit that touches the chassis, and the capacitors have physically been placed with one end close to the chassis, and the other end connected to the PCB ground.
Grounding and Decoupling: Learn Basics Now and Save Yourself …
High frequency power supply noise is best reduced with low inductance, surface-mount ceramic capacitors connected directly to the power supply pins of the IC (typically 0.01 μF to 0.1 μF). All decoupling capacitors must connect directly to a low impedance ground plane in order to …
What is a decoupling capacitor and how do I know if I need one?
The placements of (decoupling) capacitors between power and ground planes changes the transmission coefficient across a range of frequencies. Apparently using only one value for your capacitors for the entire PCB as well as lossy / high resistance capacitors is the way to go if you need to reduce EMI, however this goes against common practice ...

How to Discharge a Capacitor (with Pictures)
Grip the capacitor low on the base with one hand. You need to maintain total control over the capacitor while you discharge it, so pick it up low on the cylindrical body with your non-dominant hand. When you pick it up, make a "C" with your hand and fingers to grip it, keeping all of your fingers away from the top where the posts are.

The board level figure with decoupling capacitor is given below :-The farther the capcitor is, the more is the trace length & the more is parasictic inductance. So, it is advised to place it as close to the voltage or ground pin …
Why We Use Y Capacitors on EMI Filters to Ground
Y capacitors provide a low-impedance path to ground, filtering out high-frequency noise. They are crucial for meeting regulatory standards for EMI emissions. Their unique design ensures safety through fail-open mechanisms rather than fail-short, preventing catastrophic failures.

Positive of polarized capacitor connected to ground
For polarised capacitors they have adopted the convention that the curved plate is +ve. T1-T2 are a noise source as this is a noise generator. It is not unknown to use a reverse biased transistor junction as a white noise source. This tends to be voltage dependant and may need a minimum voltage to work. (From memory from 9 to 12V in some cases).
Capacitors grounded on both sides
A capacitor with a short to ground on both sides could mean a few things 1) The capacitor itself failed closed which is rare but whatever, not to mention easy enough to test compared to a normal failed capacitor (they normally fail the other way and their equivalent series resistance goes up and you then need an ESR meter to test properly).
Do we need capacitors to ground from USB D+/D
frequency energy to ground. These capacitors should be limited to a maximum of 50 pF and should be located as close to the microcontroller as possible. The capacitors are not required for the LPC microcontrollers to meet the "eye diagram" signal testing requirements, but improvements in noise-related problems have been reported when
