Magnetic Field A magnetic field is a region around a magnetic material or a moving electric charge within which the force of magnetism acts. Magnetic Field Lines Magnetic field lines are a visual representation of the magnetic field. They depict the direction and strength of the magnetic field. The direction of the magnetic field lines …
The Motion in a Straight Line or Rectilinear Motion refers to the motion of an object along a straight line. In this type of motion, the position of the object changes linearly with time along a specific path. Examples: A car moving along a straight road. A stone dropped from a certain height (neglecting air …

What is a Capacitor? A capacitor is a passive electrical component that stores electrical energy in an electric field. It consists of two conductive plates separated by an insulating material called the dielectric. When a voltage is applied across the plates, an electric field develops across the dielectric, causing positive charge to accumulate on one …
Maximum Power Transfer Theorem The Maximum Power Transfer Theorem is a fundamental principle in electrical engineering, particularly in the field of network theory. It states that the maximum amount of power is delivered from a source to a load when the load resistance is equal to the source resistance as seen from the load’s perspective. …
What is Signal? A signal is a function that conveys information about a phenomenon. In electrical engineering, signals are typically represented as functions of time. They can be categorized into different types based on their characteristics: Continuous-Time Signals: These are defined for every time instance and are represented as x(t). Examples include analog signals like …

An ideal current source is a theoretical concept to represent a device or circuit element that provides a constant current regardless of the voltage across it. Important Features of Ideal Current Source Constant Current Output: The current provided by an ideal current source remains constant regardless of the voltage across its terminals. This means that it …
Ideal Voltage Source An ideal voltage source is a fundamental concept in electrical engineering and in network theory. It provides a perfect, unchanging voltage to any connected circuit, unaffected by any external factors or load variations. Characteristics of an Ideal Voltage Source Constant Voltage: An ideal voltage source maintains a constant voltage across its terminals …
