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 size capacitor can i replace a 1000uf 50v with if i don't have the exact one i am working on a project and it calls for 1000uf 50v cap I know i need 50v plus but can i use 1200uf 50v or 2000uf?
You can use a larger capacitor (more uF) in the decoupling or smoothing parts of the circuit, but not in anything that is used to control the frequency response, but that is unlikely.
How does coupling capacitor couples two stages in a multi stage amplifier?
A: it could be both coupling meaning eliminate DC from the source or decoupling whereby unwanted signal is bypassed to ground

Why inductance should be low in decoupling capacitors?
Inductance should be low in decoupling capacitors because the purpose of the decoupling capacitor is to absorb voltage transients due to suddent shifts in current due to switching activities, such as in a logic gate or high speed op-amp. If significant inductance were present, the power pin on the device would be allowed to dip or rise in voltage, potentially destabilizing the circuit. As circuit switch time becomes less and less, decoupling becomes more and more important. Even a short wire has inductance, and at the higher frequencies encountered in high performance circuits, that inductance becomes a critical factor. As a result, decoupling capacitors are place right next to the device being protected, often right across the power pins.

Why PNP and NPN are used in direct coupling?
To save a decoupling capacitor & biasing resistors for the PNP.
What is the effect on voltage gain in a common emitter amplifier when the decoupling capacitor is removed?
The emitter bypass capacitor, in a typical common emitter configuration, increases gain as a function of frequency, making a high pass filter. Removing the capacitor will remove the gain component due to frequency, and the amplifier will degrade to its DC characteristics.

What is the difference between a standard capacitor and a coupling capacitor?
Coupling capacitors are used to couple different stages so as to prevent DC from the o/p of one stage to go into the i/p of the next stage. For instance in coupling two BJT (bipolar junction transistors) it is required to use coupling capacitor to allow only ac signal from the o/p of fisrt stage to go to i/p of next BJT as incoming dc can distrub the biasing of the other BJT. Bypass capacitors are used to bypass the ac signal to ground. A capacitor is connected b/w the gnd and the wire. For ac signal capacitor will behave as short and will bypass it. However dc will not be bypassed as capacitor will behave as open for DC.

Why use decopuling capsistor?
You're probably thinking of a decoupling capacitor. It acts as a filter, and prevents some manners of electric signals to make it from one part of a system to another - it decouples everything "downstream" of the component from a signal that's present "above" the component.
When was The Terminator Decoupling created?

Can you use a 25K capacitor instead of a 2.2K capacitor?
In general, no. You need to use the correct capacitor as designed for the circuit.
