This depends on what kind of circuit you have. Generally, you cannot just add a capacitor to a circuit and 'improve it'. Probably, though, you mean an amplifier, anf by improve, you mean improved frequency response. In a transistor amplifier, you sometimes want increased gain at higher frequencies. By adding a capacitor from the emitter to ground, you create a low impedance path to ground for the AC signal. This lowered emitter impedance increases the gain of the amplifier, for frequencies where the capacitor looks like a low impedance, or high frequencies.

Negative.
Including a series capacitor in the input and/or output circuit of the transistor. If the capacitor in the output circuit is omitted there will be a dc component in the output.
R for resistor, C for capacitor. RC circuit is a circuit built with a resistor and a capacitor. This circuit will have a typical pulse response that looks like exponential decaying and a typical resonance frequency.
series resonant circuit
The resistance of a capacitor is determined by its construction and materials used. Higher resistance can lead to slower charging and discharging of the capacitor, affecting the performance of the capacitor in an electronic circuit by potentially causing delays in signal processing or affecting the overall efficiency of the circuit.
The relationship between capacitor resistance and the overall performance of an electronic circuit is that the resistance of a capacitor affects the charging and discharging times of the capacitor, which can impact the timing and stability of the circuit. Higher resistance can lead to slower charging and discharging, potentially affecting the circuit's functionality and efficiency.
When a capacitor is connected in parallel with a battery in a circuit, it can store and release electrical energy. This can affect the overall performance by smoothing out voltage fluctuations, filtering out noise, and improving the stability of the circuit.
A small capacitor can be part of an integrated circuit.
When a capacitor is connected to a circuit, the current flow through the capacitor initially increases and then decreases as the capacitor charges up.
What happens to the current in a circuit as a capacitor charges depends on the circuit. As a capacitor charges, the voltage drop across it increases. In a typical circuit with a constant voltage source and a resistor charging the capacitor, then the current in the circuit will decrease logarithmically over time as the capacitor charges, with the end result that the current is zero, and the voltage across the capacitor is the same as the voltage source.
The magnetic field between capacitor plates does not have a significant effect on the overall performance of the capacitor. The main factors that affect a capacitor's performance are its capacitance, voltage rating, and dielectric material.
Any circuit using a capacitor will not work if the cap is short-circuited.
paper capacitor
when we replace the resistor with a capacitor ,the current will flow until the capacitor charge when capacitor will fully charged there is no current through the circuit because now capacitor will act like an open circuit. for more info plz E-mailt me at "zaib.zafar@yahoo.com"
The formula to calculate the maximum charge on a capacitor in an electrical circuit is Q CV, where Q represents the charge on the capacitor, C is the capacitance of the capacitor, and V is the voltage across the capacitor.
when a capacitor is connected to earth the potential of capacitor becomes zero. as a result all the charge residing on the conductors of a capacitor passes away and the final charge on capacitor becomes zero
