Overview
This chapter explores the fundamental concepts of electric current, its behavior through conductors, and the various laws governing electrical phenomena. We learn how charge carriers move through materials, the relationship between voltage and current (Ohm's law), and practical applications in elect
Key Concepts
Electric current I is defined as
Electric current I is defined as the rate of flow of charge: I = q/t. In conductors, free electrons constitute the current. The SI unit is ampere (A).
When electric field is applied
When electric field is applied, electrons drift with average velocity Vd = I/(nAe), where n is electron density per unit volume. Current density J = I
States that current through a conductor
States that current through a conductor is directly proportional to applied voltage: V = IR, where R is resistance. Valid for ohmic materials where I-
Resistance R = ρl/A depends on
Resistance R = ρl/A depends on material (resistivity ρ), length l, and cross-sectional area A. Resistivity is intrinsic material property with unit Ω⋅
Power dissipated in resistor
Power dissipated in resistor: P = VI = I²R = V²/R. Energy consumed in time t: W = Pt. In resistors, electrical energy converts to heat energy through
Learning Objectives
- Understand the concept of electric current as the flow of charge carriers and its measurement
- Analyze drift velocity of electrons and its relationship with current density
