The capacitor blocks the DC portion of the signal and therefore only the AC portion is amplified. i.e if the signal applied exists at a 2 Volt level for instance, after the capacitor the 2 Volts will be trimmed off.
The main role of dielectrics in capacitors is to increase the value of capacitance of the capacitor.
A capacitor is a device that stores electric potential energy and charge. Unlike batteries, capacitors do not involve chemical reactions. They merely encompass the movement of charged particles, so they can be charged and discharged very quickly. This important property gives them many useful applications. They are used as electrical flash units in photography, lasers, air bag sensors, radio receivers, and television receivers. Most importantly, they are used in alternating-current circuits, which play a crucial role in most household and industrial power-distribution systems.
In transistors, current gain plays a significant role. In h parameters, one of the parameters is hfe which is current gain. It is easier if the parameters chosen represent some significant properties of the device. Some other parameters of importance in transistors are input resistance hie and output resistance 1/hoe.So it makes sense to analyse transistors with h parameters.

Electronics engineering mainly deals with things like power,machines etc. And role of engineering drawing in electronics engineering can be defined as for making blue prints of the model.
The main role of dielectrics in capacitors is to increase the value of capacitance of the capacitor.
Feed back resistance plays the vital role of controlling output of the OPAMP. Also surrounding temperatures affects the out put of OPAMP. ANSWER: The gain drives the output to either B+ or B- minus the saturation of the output circuitry
Gram
it has a role in water output.
The capacitor charges up with the current flowing through a resistor. The time taken is well defined by the capacitance and the resistance, and these components control the frequency.
capacitor and copper winding
It is an input device.
Capacitance and voltage may be varied independently of one another, but the outcome depends exactly what the circuit is and what role this capacitor plays. If it's a timing capacitor, the time constant will increase. Certainly the impedance will change in a circuit where it's required to decouple a rail with ripple present; as a filter or as a coupling capacitor.

Capacitors are generally used in high powered automotive sound applications. The capacitor acts as a storage for power. When peak parts of a music program are played and extra power is needed to drive the amplifier and speaker, the power is drawn from the capacitor. This puts less strain on the car's battery and alternator.
The role is to monitor the input, process, and output so that the system can adjust itself to meet the goal.
