Relay

This animation shows how a relay works as an electrically operated switch. Relays allow a low-voltage control signal to switch high-voltage or high-current loads safely. They...

Circuit Breakers

This animation shows the internal mechanism of a circuit breaker and how it automatically cuts off electrical power during a fault. A circuit breaker detects...

Transformers

This animation explains how a transformer changes the voltage level of alternating current (AC). Transformers work on the principle of electromagnetic induction, transferring electrical energy...

Distribution System

This animation shows how electricity is delivered from the local substation to homes, shops, and small industries. The distribution system is the final stage of...

Transmission Lines

Here is your app-ready article for Transmission Lines, written in the same clean, structured format as your other topics. Perfect for your “Power System”...

Generation of Electricity

This animation shows how a thermal power plant generates electricity by converting heat energy into electrical energy. Fuel is burned to produce heat, which turns...

Voltage Divider Rules

This diagram explains the Voltage Divider, a basic DC circuit used to split a single supply voltage into smaller, desired output voltages. A voltage divider...

Ohm’s Law

Ohm’s Law This animation demonstrates Ohm’s Law, the fundamental relationship between voltage (V), current (I), and resistance (R) in a DC circuit. It shows how changing...

Impedance Analysis

This diagram explains the impedance behavior of AC circuits, showing how voltage and current signals can differ in magnitude and phase. Impedance represents the total...

Capacitor

A capacitor is an electrical component that stores and releases energy in the form of an electric field. When connected with an inductor, it...

Three Phase Automatic Transfer Switch (ATS) Connection

This diagram shows a Three Phase Automatic Transfer Switch (ATS) system — a smart electrical setup that automatically switches the power supply between normal...

Inductor

An inductor is a passive electrical component that stores energy in the form of a magnetic field when electric current flows through it. It...

Table 310.15(B)(3)(a) — Adjustment Factors

Overview When more than three current-carrying conductors are installed together in the same raceway, cable, or bundled group, their ability to dissipate heat decreases. To prevent...

Table 310.16 — Ampacity of Conductors

Purpose NEC Table 310.16 provides the allowable ampacity (current-carrying capacity) of insulated conductors rated 0 – 2000 volts. It is one of the most used tables...

Article 215 – Feeders

Purpose Article 215 of the National Electrical Code® (NEC®) establishes the requirements for the installation, sizing, and protection of feeder circuits — the conductors that...
