2. Parasitic capacitance - Wikipedia

   en.wikipedia.org/wiki/Parasitic_capacitance

   The screen grid was added to triode vacuum tubes in the 1920s to reduce parasitic capacitance between the control grid and the plate, creating the tetrode, which resulted in a great increase in operating frequency. [3] In bipolar junction transistors, the parasitic capacitances between the base and collector or emitter have voltage dependence ...

3. Chassis ground - Wikipedia

   en.wikipedia.org/wiki/Chassis_ground

   A chassis ground is a link between different metallic parts of a machine to ensure an electrical connection between them. [1] Examples include electronic instruments and motor vehicles. Usages

4. Decoupling capacitor - Wikipedia

   en.wikipedia.org/wiki/Decoupling_capacitor

   A decoupling capacitor provides a bypass path for transient currents, instead of flowing through the common impedance. [1] The decoupling capacitor works as the device’s local energy storage. The capacitor is placed between the power line and the ground to the circuit the current is to be provided.

5. Ground (electricity) - Wikipedia

   en.wikipedia.org/wiki/Ground_(electricity)

   The use of the term ground (or earth) is so common in electrical and electronics applications that circuits in portable electronic devices, such as cell phones and media players, as well as circuits in vehicles, may be spoken of as having a "ground" or chassis ground connection without any actual connection to the Earth, despite "common" being ...

6. Capacitance - Wikipedia

   en.wikipedia.org/wiki/Capacitance

   [1]: 237–238 An object that can be electrically charged exhibits self capacitance, for which the electric potential is measured between the object and ground. Mutual capacitance is measured between two components, and is particularly important in the operation of the capacitor , an elementary linear electronic component designed to add ...

7. Ground loop (electricity) - Wikipedia

   en.wikipedia.org/wiki/Ground_loop_(electricity)

   The ground loop still exists, but the two sides of the loop are close together, so stray magnetic fields induce equal currents in both sides, which cancel out. Break in the shield Create a break in the signal cable shield conductor. [5] The break should be at the load end. This is often called ground lifting. It is the simplest solution; it ...
