What is the effect on the circuit if we add a capactior in parallel with another capacitor?

Capacitors in parallel simply add up, similar to resistors in series...
CTOTAL = sumI=1-N (CI)
Capacitors in series work like resistors in parallel...
CTOTAL = 1 / sumI=1-N (1 / CI)

Why a capacitor of higher value is preferable?
It can hold a very large amount of charge and release the same over along period of time. It depends in what circuit you are using it. For power supply decoupling and regulation, bigger is better. If you change the capactior value in a timing or tuned circuit, it will not behave as designed.
Why is the parallel resonant circuit called an rejector circuit?
THE PARALLEL rlc CIRCUIT IS CALLED A REJECTOR CIRCUIT BECAUSE IT REJECTS DOWN THE CURRENT. THE REASON IS AT RESONANCE THE IMPEDENCE OF THE CAPACITOR BECOMES EQUAL TO THAT OF THE INDUCTOR SO NO CURRENT FLOWS. AT LOW FREQUENCY THE CAPACITIVE REACTANCE IS LOW SO ALL THE CURRENT FLOWS THROUGH THE INDUCTOR AND WHEN THE FREQUENCY IS HIGH ALL THE CURRENT WILL FLOW THROUGH THE CAPACITOR BECAUSE AT THAT POINT THE REACTANCE OF THE CAPACITOR IS LOW. SO WE OBTAIN A V-SHAPED GRAPH WITH THE PEAK OF V INDICATING THE REJECTION OF CURRENT.
What does a capacitor do in an amplifier circuit?
not sure
Each branch in a parallel circuit may hold several resistors yes or no?
No. What you are describing is a series-parallel circuit, not a parallel circuit.
In a capacitor circuit load angle is?
Negative.
A circuit contains a 10 pF capacitor and a 50 pF capacitor connected in parallel.What is the total capacitance of this circuit?
When capacitors are connected in parallel, the total capacitance in the circuit in which they are connected is the sum of both capacitances. Capacitors in parallel add like resistors in series, while capacitors in series add like resistors in parallel.
Why inductor use in series capacitor in parallel?
That depends on the type of circuit you are talking about. Sometimes both an inductor and capacitor are both in parallel with each other. This is called a tank circuit. Sometimes they are both used in series. These are both examples of resonant circuits. Sometimes the inductor can be in parallel with an applied voltage and the capacitor in series. This is a form of high pass filter. On the other hand, the inductor can be in series and the capacitor in parallel to for a low pass filter.

What is difference between acceptor circuit and rejector circuit?
Acceptor circuit are series circuit in which indactor and capacitor are join in series there is single path available for flow of current.while in rejector circuit inductor and capacitor are join in parallel more then one path are available for flow of current .
Lrc parallel circuit?
LRC parallel circuit contains its component in parallel connectio. It contains inductor, resistor and a capacitor. A parallel circuit is a closed electrical circuit in which the current is divided into two or more paths and then returns via a common path to complete the circuit
Uses of gang capacitor?
Gang capacitors are commonly used in radio tuners/receivers. Radio tuners/receivers have formation of LC(inductance and capacitor). Here this circuit has one fixed inductance and capacitor parallel with gang capacitor. Normally gang capacitor used in superhetrodyne receiver.
What is the use of decoupling capacitor?
The purpose of a decoupling capacitor is to decouple one part of a circuit from another. Decouple means to provide isolation. It's used to keep unwanted interference from one part of a circuit from impacting another.
What is another name for a series -parallel circuit?
series other name current series and parallel is voltage
Is capacitor a part of integrated circuit?
A small capacitor can be part of an integrated circuit.

When a parallel LC circuit is tuned to resonance will the current be at a maximum or a minimum?
Inside the circuit loop between the inductor and capacitor the current will be at maximum. Outside the circuit the current through the LC tank circuit will be at minimum. It depends on where you are measuring it.
What are the two kinds of electrical circuit?
There are four types of circuit: series, parallel, series-parallel, and complex.
