Chapter 14: RC Circuits
14.1 Introduction In this chapter, we will explore RC circuits, which consist of resistors (R) and capacitors (C). These circuits are fundamental in understanding the behavior of capacitors in the presence of resistive elements and the resulting time-dependent voltages and currents. RC circuits play an essential role in various applications, including filtering, integration, differentiation, and…

Magnetoresistance
Introduction Magnetoresistance is the property of a material to change its electrical resistance in response to an applied magnetic field. This quantum mechanical phenomenon has profound applications in modern electronics and computing. Basic Explanation When a magnetic field is applied to a conductive material, the trajectories of the charge carriers (electrons or holes) can be…

Chapter 10: Resistance and Resistivity
10.1 Introduction to Resistance Resistance is a property of a material that opposes the flow of electric current. It is a measure of how difficult it is for current to pass through a conductor. In this chapter, we will explore the concept of resistance and its relationship to current, voltage, and the physical properties of…

Ohm’s Law
Introduction Ohm’s law is a fundamental principle in the field of electronics and electrical engineering. Named after the German physicist Georg Simon Ohm, it describes how current, voltage, and resistance interact in an electrical circuit. Definition and Equation Ohm’s law states that the current flowing through a conductor between two points is directly proportional to…
