You can see that the ground plance stops short of the USB socket. The large hole is where the tabs for the USB shield to have a mechanical connection to the PCB. R1 is then connecting the shield to GND, and capacitor C3 is doing the same on the other connection. The shield is connected to ground via the 100k res/100nF cap.

The gist of a capacitor''s relationship to voltage and current is this: the amount of current through a capacitor depends on both the capacitance and how quickly the voltage is …
Design Guide: Resistance Grounding In Electrical System
Ohms law (R = V / I) state that if we know the phase to ground voltage and the desired current we can directly compute for the grounding resistance. But in case of grounding resistance we need to consider the line to …
Fundamentals | Capacitor Guide
What is a Capacitor? A capacitor is a two-terminal passive electrical component that can store electrical energy in an electric field.This effect of a capacitor is known as capacitance. Whilst some capacitance may exists between any two electrical conductors in a circuit, capacitors are components designed to add capacitance to a circuit.
How to measure ripple for better design outcomes
peak ripple. Output-voltage ripple is the alternating current (AC) component of the direct current (DC) output voltage. It''s generated by a combination of factors, including the output capacitor ''s equivalent series resistance (ESR), the voltage drop across the output capacitance, duty cycle and switching frequency.
Should chassis ground be attached to digital ground?
$begingroup$ @DavidKessner when signal ground is shorted to chassis ground in multiple points on the PCB (i.e. via the mounting holes as you suggest), is there a worry that the signal GND current will flow through the chassis? I think the answer to this is "no, the current will flow through the PCB because it will want to flow through the path of lease …

Grounding a capacitor?
Notice that the capacitor symbol shows a gap between two plates. That''s literally what a capacitor is. A capacitor doesn''t allow current to flow through it. It only allows current to cause a charge buildup on it. You''re converting excess voltage and current into an ...

Optimal neutral ground resistor rating of the medium voltage systems in power generating stations …
The resistor must be sized to ensure that the ground fault current limit is greater than the system''s total capacitance-to-ground charging current. If not, then transient overvoltages can occur.[ Citation 3 ] Furthermore, NGR selection is a comprehensive task which involves many aspects of power system as shown in Figure 7 .
