3rd Harmonics
3rd Harmonics Interactive Simulation ⚡ 3rd Harmonics Interactive Simulation See how the 3rd harmonic changes an AC waveform and why it matters in electrical systems. What is a 3rd Harmonic? A third harmonic is a sinusoidal component whose frequency is three times the fundamental frequency. For a 50 Hz electrical system, the 3rd harmonic is […]

1st Harmonic Interactive Simulation ⚡ 1st Harmonic — Interactive Electrical Simulation Explore the fundamental frequency, waveform, causes and possible effects of harmonic-related electrical distortion on electronic and electrical machinery. What is the 1st Harmonic? The 1st harmonic is the fundamental component of a periodic electrical waveform. If the fundamental frequency is 50 Hz, the 1st […]
Electric Charge
Electric charge is a fundamental property of matter that causes objects to experience electrical forces. There are two types of electric charge: positive and negative. Protons carry positive charge, while electrons carry negative charge; neutrons have no electric charge. Like charges repel each other, while opposite charges attract each other. The SI unit of electric […]
Grounding & Earthing
Grounding and earthing are electrical safety methods that provide a low-resistance path for unwanted electrical current to flow safely into the earth. In everyday electrical discussions, the terms are often used interchangeably. The basic idea is to prevent dangerous voltage from remaining on exposed metal parts of equipment such as washing machines, refrigerators, electrical panels, […]
Electrical Frequency
Electrical frequency is the number of complete cycles of an alternating current (AC) or voltage waveform that occur in one second. It is measured in hertz (Hz), where 1 Hz means one complete cycle per second. For example, a 50 Hz AC supply completes 50 cycles every second, while a 60 Hz supply completes 60 […]
Conductors
Conductors are materials that allow electric current to flow through them easily because they contain many free electrons that can move from one atom to another. Common electrical conductors include copper, aluminium, silver, and gold. Copper is widely used in electrical wiring because it has excellent conductivity, is relatively affordable, and is easy to work […]
Series & Parallel Circuits
Series & Parallel Circuits In a series circuit, electrical components are connected one after another in a single path for current. The same current flows through every component, so if one component fails or the circuit is opened, the entire circuit stops working. In a parallel circuit, components are connected across separate branches, giving current […]
AC vs DC Electricity
AC (Alternating Current) is the type of electricity normally supplied to homes and buildings. In AC electricity, the direction of current changes periodically, making it practical for transmission over long distances and distribution through the electrical grid. Household appliances such as lights, fans, refrigerators, televisions, and air conditioners are generally designed to operate from the […]
