Page 2: Circuit Analysis and Basic Laws

This section covers essential electrical laws and circuit configurations, providing a foundation for understanding more complex circuit behavior.

Definition: Series circuits have components connected end-to-end, while parallel circuits have components connected across the same voltage points.

Highlight: Key electrical laws covered include:

• Ohm's Law relating voltage, current, and resistance
• Kirchhoff's Voltage Law for circuit loops
• Current behavior in series and parallel circuits

Example: In a series circuit, the current remains constant throughout all components, while voltages add up to equal the source voltage.

Page 3: RC Series Circuit Charging Analysis

This page delves into the modèle du circuit RC en série, specifically focusing on the charging process.

Definition: The time constant (τ) of an RC circuit is defined as the product of resistance (R) and capacitance (C), measured in seconds.

Highlight: The charging equation for capacitor voltage is: Uc = E(1 - e^(-t/RC))

Example: At one time constant (t = RC), the capacitor voltage reaches approximately 63% of the supply voltage.

Page 1: Fundamentals of Electrical Systems

This page introduces the fundamental concepts of electrical current and capacitors. The content focuses on defining basic electrical quantities and components.

Definition: Electrical current intensity (i) is defined as the flow rate of electrical charge, measured in Amperes (A).

Vocabulary: Capacitor - An electrical component that stores electrical charge between two conducting plates separated by an insulating material.

Highlight: Capacitor characteristics depend on three key factors:

• Distance between plates
• Surface area of plates
• Type of insulating material (dielectric)

Example: Common capacitor values are typically expressed in microfarads (μF), where 1 μF = 1 × 10⁻⁶ F
