Experimentally check the dependence of the capacitance of the capacitor on its geometric characteristics. To do this, take two metal flat plates and charge one of them (for example, rub a glass daddy on silk), bring the other plate close to it and then ground it. Connect the plates with a voltmeter. Reduce the distance between the plates and watch the change in the voltmeter readings. Move the plates relative to each other and also watch the change in the voltmeter readings. Draw conclusions.
With a decrease in the distance between the plates, the electrical capacity of the capacitor increases, and the voltage on the voltmeter 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.
