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...
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...
Semiconductor
A semiconductor is a material that has electrical conductivity between that of a conductor and an insulator. It can conduct electricity under certain conditions,...
Staircase Wiring Connection
This diagram shows a staircase wiring circuit, a smart setup that allows you to control a single light from two different switches — one...
Parts of an Oil-Filled Transformer
This diagram shows the internal and external parts of an oil-filled power transformer, an essential device used to step up or step down voltage...
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...
Simple Switch Board Wiring Connection
This diagram explains the basic switch board wiring used in homes and offices. It shows how multiple sockets and a switch are connected to...
AC Voltage
Alternating Voltage (AC Voltage): Voltage that changes direction periodically, usually in a sinusoidal pattern.
A sine wave represents AC voltage and current.
Voltage and current rise...
Ceiling Fan Wiring Connection with Regulator and Capacitor
This diagram shows the complete fan wiring connection using a switch, regulator, and 3.3µF capacitor. It demonstrates how to properly wire a ceiling fan...
Square Waveform
What is a square wave
A square wave is a periodic waveform that switches between two levels (for example +A and −A, or “on” and...
Alternating Current
Alternating current (AC) is a type of electric current where the flow of electrons, or charge carriers, periodically changes direction. Unlike direct current (DC),...
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...
