Abstract
This document provides a comprehensive analysis of electrical circuits, including series circuits, voltage measurements, and the application of laws such as the law of additivity of voltages and the law of uniqueness of intensities. It also covers the use of ammeters and voltmeters in circuit analysis.

[...] Normalized electrical circuit diagram: 1.b. The voltmeter is connected in derivation (additional wires are required). The V terminal on the + side of the generator. 2. We are in a series circuit, the motor is short-circuited (by a wire). In a series circuit, we must apply the law of additive voltages: « The voltage in the main branch (that of the battery) is equal to the sum of all the other voltages. Here the voltage of the battery is equal to the voltage of the lamp. [...]
[...] Laws of electrical circuits Objectives: Exercise 1 - Pocket Lamp Exercise 2 - Electrical Circuit Exercise 3 - Voltage Measurements Exercise 4 - Switch and Multimeter Exercise 5 - Using a Multimeter Exercise 1 : 1. a. Standardized Diagram battery, a switch, and a lamp in series): 1.b. The ammeter is connected in series, it must be inserted directly into the circuit, for example in this way: We don't forget to specify the ammeter terminals side + of the generator). 2.a. [...]
[...] Note: U is the symbol for voltage. So here: U(battery) = U(led + U(led 12.06 = 6.09 + U(led So: U(led = 12.06 - 6.09 = 5.97 V 4. The two lamps are in a series circuit, the law of uniqueness of intensities tells us that: 'in a series circuit, the intensity that crosses all the poles is the same at every point in the circuit' So yes the two intensities are equal. Exercise 4 1. Diagram: 2. We apply the law of additive tensions: UG = UM + UL + UR 12,1 = UM + 4,6 + 3,2 So UM = 12,1 - = 4,3V La tension del motor es de 4,3 V. [...]
