Parallel capacitors, for example bypass capacitors, pose a challenge to electrically identify individual capacitor values as the capacitance across the two nodes is the sum of all the capacitance.
12.
In these applications, the decoupling capacitors are often called " bypass capacitors " to indicate that they provide an alternate path for high-frequency signals that would otherwise cause the normally steady supplies to move.
13.
In the transitron circuit, the screen and suppressor grids are coupled with a bypass capacitor ( " C2 " ) which has a low impedance at the oscillation frequency, so they have a constant potential difference.
14.
When the grid leak stage had a transformer input, the valve grid connected to one end of the transformer secondary, and the other end of the secondary went to ground via the grid leak resistor and a small bypass capacitor.
15.
More modern probe designs use a thick-film electronic circuit in the head that combines the 9 megohm resistor with a fixed-value bypass capacitor; they then place a small adjustable capacitor in parallel with the oscilloscope's input capacitance.

:: I would find it very hard to draw a connection between failure of the decoupling capacitors ( bypass capacitors / bulk storage capacitors ) and the release of magic smoke from a stick of RAM . I think it's entirely likely that your CPU chip survived.
17.
In that case a bypass capacitor is not needed ( although in practice a small one of around 0.68 to 1 nF is often used to help improve quality ), but instead a 10-100 k? resistor must be added in parallel with the earphone's input.
18.
The chassis was maintained at RF ground ( for shielding ) by a bypass capacitor ( typically 0.05 �F to 0.2 �F ) usually with a resistor connected across it ( typically 220 k? to 470 k?, although values as small as 22 k? were sometimes used or the resistor was simply omitted ).
19.
Should I use a bypass capacitor between emitter and ground or can I use an appropriate voltage divider between + V and ground with the central node connected to the collector in order to establish a constant voltage and, therefore, a constant IC ?

Remember, the gain of a common emitter amplifier is ( roughly ) the ratio of the collector resistance over the total emitter resistance ( counting the internal R E of the transistor plus any external resistance / impedance that you add ); the bypass capacitor brings the total emitter resistance down to the typical few ohms or tens of ohms R E inherent in the transistor itself.
