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...
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
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...
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...
A capacitor is an electrical component that stores and releases energy in the form of an electric field. When connected with an inductor, it...
This diagram shows a Three Phase Automatic Transfer Switch (ATS) system — a smart electrical setup that automatically switches the power supply between normal...
An inductor is a passive electrical component that stores energy in the form of a magnetic field when electric current flows through it. It...
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...
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...
Purpose
Article 215 of the National Electrical Code® (NEC®) establishes the requirements for the installation, sizing, and protection of feeder circuits — the conductors that...
Every receptacle, light fixture, and hardwired appliance in a building is served by a branch circuit. Understanding what a branch circuit is — where...
Purpose
Article 200 of the National Electrical Code® (NEC®) defines the rules for identifying, connecting, and using grounded conductors — commonly known as neutral conductors.
These...
