André-Marie Ampère

André-Marie Ampère
1775 — 1836
Electrical Quantities, Direct Current (DC), Electrical Circuits, Measurement Technology

André-Marie Ampère was one of the first scientists to reveal the connection between electricity and magnetism. His experiments showed that an electric current creates a magnetic field and can interact with other currents. Today, the unit used to measure electric current — the ampere — bears his name.

Electric Current — The Movement of Electric Charges

Electric Current — The Movement of Electric Charges

Why does a light bulb turn on almost instantly when you flip a switch? What actually happens inside the wires when electric current flows? In this article, we explain what physicists mean by electric current, how random electron motion differs from an organized flow of charges, and why this movement allows energy to travel through wires. You will also learn what happens inside a conductor, how current is measured, and why electrical wires can heat up.

What Is Electricity?

What Is Electricity?

Why does a light bulb turn on instantly, and why does a wire heat up? In this article, we’ll explore what actually moves inside wires, how random motion differs from electric current, and why everything around us works thanks to the controlled movement of electric charges.

Alessandro Volta

Alessandro Volta
1745 — 1827
Electrochemistry, Direct Current (DC), Power Sources

Alessandro Volta was the first scientist to create a stable source of electric voltage. His invention, the voltaic pile, marked the beginning of electrochemistry and modern electrical engineering. We explore why this discovery became the foundation of electronics.
