Today, various modern pedagogical technologies are widely used in the educational process, which activate the educational activities of students while maintaining the traditional form of lessons. In most cases of traditional classes, the teacher speaks. This weakens student activity to some extent. In non-traditional classes, in contrast to the traditional lesson, the harmony of image and sound increases the activity of students and their interest in the topic under way. The resulting knowledge serves to be preserved in his memories for the long term. The most important thing is to motivate students to work independently and think. Taking advantage of the convenience and capabilities of modern pedagogical technologies, when students are visually explained the physical processes and phenomena, the sum of the knowledge, skills and qualifications that they acquire is embodied. This leads to higher efficiency of teaching in the educational process [1]. To this end, in this article we will use the "I knew, I want to know, I learned" method to strengthen the most fundamental issues of the topic superposition principle of electric field voltage.
I knew, I wanted to know, I learned method-this method can be used in a new knowledge-giving type lesson [2]:
Step 1: A new topic is written on the board. Student notebooks are offered to write "I knew" what they know about this new topic. Three minutes are given for this. A presentation is held. During the presentation, readers will tell what they know about the new topic. During the presentation, the rule of not repeating thoughts back by groups is strictly observed.
Step 2: Students write "I want to know" in their notebooks. Then it is proposed to write what he wants to know about the new topic. This is given three minutes. A presentation is held. After that, information is explained by the teacher, which students want to know about the new topic.
An electric field is also generated by a single point charge, but often an electric field is mainly generated by a system of charges. If we introduce a Test charge at any point in the field formed by the charge system, it is influenced by forces from each charge. The equal impactor of
all forces acting on the test charge is equal to: F = F[ + F2 +... + Fn
Then the voltage of the field at the point where the charge is introduced is:
= ^ + Î + + Î = + + + ^ <1S Cls Cls Cls Cls
E = El+E2 + ...+ En (1) - this formula is called the superposition principle of an electric
field, and it is defined as: the electric field voltage generated by a system of charges at a point is equal to the vector sum of the field voltage of each charge entering the system at that point. (The word superposition means join or fall over). The electric field voltage of a point charge is found
- 1 _mn? N ■ C2
using the formula: E = k(2) Here: k =-= 9-109-5—;^= 8,85-10-
r C N - m
The condition for the electric field to be homogeneous holds invariant without the coordinate being dependent: E = const
When the voltage vector is the same at all points, such a field is called a homogeneous electric field.
Resultant electric field voltage
Where the field is generating a 2-point charge, according to the superposition principle, the resultant field voltage is represented by the formula E = El+E2 [3].
The resulting electric field voltage modulus is found using the formula:
E = Je? + E2 + 2 - E - E - cos« (3)
For some private values of a (3) we make the formula look simple:
1) a = 0°; when the electric field voltage vectors are in the same direction: E = El+E2
71
2) a = — = 90 ; where the electric field voltage vectors are in the mutually perpendicular
direction: E = <J Ef + E2
3) a = 7i = 180°; where the electric field voltage vectors are in the opposite direction:
E = |Ei -E2I
Step 3: Students are invited to write "I learned". Students write in their notebooks what they understand on a new topic. To do this, they are given ten minutes. After ten minutes have elapsed, a presentation is held. The new topic is told by students.

In all steps, students are required to follow the rule of listening to each other. And by the teacher, the materials left unspoken on the new topic are filled in on time.
