The "requirement" of using two capacitors with the crystal in the 8051 is complicated, and based on many factors, such as series resistance, the design of the parallel resonant feedback circuit, stray or parasitic capacitance, startup stability, etc. Insight can be gained from Intel's Application Note AP-155 but, in the final analysis, from a purely pragmatic standpoint, the requirement is there simply because "Intel says so". Use the circuit from the data sheet.

by using capacitor on the line we can reduce spike current or we can use a capacitor bank for the rated line capacity.
myler film /myler capacitor is specially designed for low inductance and low resistance,so it has an prpoperty of fast discharging energy
No. The purpose of the zener diode is to clip (turn on) at a certain voltage. A capacitor will not exhibit this behavior.
A: The purpose it to block the capacitor from discharging to the source
it provides stabilization to oscillator
for accurate time rc oscillator is common in non time critical stuff
Just use any two of the three terminals that are available, this will give you a single phase capacitor.
There is no formal adc input on the 8051. However, the CMOS version of the chip can use a technique involving a resistor, diode, and capacitor, along with a bidirectional pin (or one output pin and one input pin) to implement a "quick and dirty" adc function. You discharge the capacitor and then let it charge to the voltage of the input. You measure the time it takes to see the input pin change, and you calculate the input voltage.
capacitor is charge holding device ,it holds charge on two plates named as +ve and -ve
Use of rvt in capacitor bank
In general, no. You need to use the correct capacitor as designed for the circuit.
we can use both timers ...
No
The 8051 is a microcontroller, not a microprocessor. To add or subtract, use the ADD or SUBB opcodes.
The products that uses the capacitor are filters and oscillators.
