The Important Role of a Bypass Capacitor
To ensure that expensive, high-speed components are provided with clean power consistently, designers add bypass capacitors as close to the IC power input leads as possible. The bypass capacitor acts as a filter, providing infinite resistance to steady-state voltage and bypassing high-frequency noise.
Feedback Resistor and Capacitor in amplifier
Feedback can be used in any kind of amplifier circuit, not just in op-amp circuits. Feedback can be achieved by any component or network that will deliver a portion of the output signal back to the input; resistors and capacitors and networks built from them just happen to be common choices.

What are capacitors? In the realm of electrical engineering, a capacitor is a two-terminal electrical device that stores electrical energy by collecting electric charges on two closely spaced surfaces, which are insulated from each other. The area between the conductors can be filled with either a vacuum or an insulating material called a dielectric. …

Capacitor in Electronics
When a capacitor is connected to a power source, electrons accumulate at one of the conductors (the negative plate), while electrons are removed from the other conductor (the positive plate). This creates a potential difference (voltage) across the plates and establishes an electric field in the dielectric material between them.
How RF Amplifiers Work: RF Amplifier Functions

Are car audio capacitors good or bad, and what''s the deal with …
Capacitors are advertised as a way to store extra current and deliver it to your amplifiers when they pull large amounts of power to stabilize your electrical system and current draw. That''s all good and well in theory but in reality it just makes things worse (kind of like "Trickle-down economics").

Amplifier in electronics
These amplifiers increase the voltage level of the applied input signal and generate at the output. 2. Large signal amplifiers or Power amplifiers. These are the amplifiers that produce a large signal at the output by converting dc power into ac power. Power transistors are basically employed in power amplifiers. These are majorly classified as:
The critical contribution of coupling capacitors in amplifier sound
Over the years, with much experimenting and listening, I have found that a very major part of amplifier sound quality is directly due to the input coupling capacitors used. This is equally true for the output coupling capacitors of the preamp. Certainly the designer of the circuitry must do the job properly, but given that this is accomplished, and given that the amplifier …
What Is a Power Amplifier and How Is It Used?
Amplifiers generate heat. Housing the amplifier circuitry and power supply in a separate device may be desired, rather than cramming it in the same cabinet as other receiver-type functions, especially when lots of amplifier output power is needed.; A separate preamp and power amp results in more equipment and cable clutter.
