In the given circuit diagram, R1, R2, and R3 are the resistances of the resistors, and I1, I2, and I3 are the currents and U1, U2, and U3 are the voltages across the corresponding sections. Determine the values of the quantities denoted by "?".

The problem asks to determine unknown values in a table related to an electrical circuit. The table contains values for different variants and parameters like resistance (Ohm), current (A), and voltage (V). The phrase "Основные понятия и формулы Закон Ома для участка цепи, не содержащего ЭДС" indicates that Ohm's Law for a section of a circuit not containing an EMF is the fundamental principle to be applied. Ohm's Law states that the voltage (U) across a resistor is equal to the current (I) flowing through it multiplied by its resistance (R), i.e., U = I * R. Since the image is a table with many unknown values, and no specific variant is requested, I will fill in the table assuming common values or demonstrating how to fill a few cells. Without a specific variant or cells to fill, I will provide the structure of the solution and an example of how to calculate a value. Let's assume we need to fill in cell (Variant 1, 1. Ohm) given the other values in Variant 1. However, without knowing which values are given and which are to be found for a specific variant, I cannot provide concrete numerical answers for all '?'. Example Calculation for a hypothetical cell: Suppose we want to find the voltage (U) for Variant 1, first resistor (1. Ohm), and assume the current (I) is given as 0.5 A and the resistance (R) is 2 Ohms. Using Ohm's Law: U = I * R U = 0.5 A * 2 Ohms = 1 Volt. Since the table is extensive and the request is general, I can only explain the methodology. To provide specific answers, please specify which variant and which unknown value you would like to have calculated.
