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.

How do you reduce spike current?
by using capacitor on the line we can reduce spike current or we can use a capacitor bank for the rated line capacity.
What is the use of mylar capacitor?
myler film /myler capacitor is specially designed for low inductance and low resistance,so it has an prpoperty of fast discharging energy
Can you use a capacitor instead of zener diode in biased clipping circuit?
No. The purpose of the zener diode is to clip (turn on) at a certain voltage. A capacitor will not exhibit this behavior.
What is the use of diodes in doubler voltage?
A: The purpose it to block the capacitor from discharging to the source
Why you use capacitor with crystal in microcontroller circuit?
it provides stabilization to oscillator
Why you use crystal in 8051 microcontroller?
for accurate time rc oscillator is common in non time critical stuff
How can you use a 3 phase capacitor as a single phase capacitor?
Just use any two of the three terminals that are available, this will give you a single phase capacitor.
Is adc present on chip in 8051 or not?
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.
What is the use capacitor?
capacitor is charge holding device ,it holds charge on two plates named as +ve and -ve

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.

we can use both timers ...
Can you use a run capacitor in place of a start capacitor?
No
How do you add and subtract 16 bit numbers using 8051 microprocessor?
The 8051 is a microcontroller, not a microprocessor. To add or subtract, use the ADD or SUBB opcodes.
