Prove that from this experience the conclusion follows: with a decrease in the area of the plates, the electrical capacity of the capacitor decreases.

The capacitance of a capacitor is determined by the expression:
C = q / U
Because the charge on the plates does not change, and the voltage increases with a decrease in the overlap area of the plates, then the electrical capacity decreases.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
