How does sound gets amplified through a speaker?

Speakers contain an electromagnet: a metal coil which creates a magnetic field when an electric current flows through it. This coil behaves much like a normal (permanent) magnet, with one particularly handy property: reversing the direction of the current in the coil flips the poles of the magnet.Inside a speaker, an electromagnet is placed in […]

Every electronics engineering should know basic functions of Electronic Devices.

Electronic devices perform three main functions: (1) amplification, (2) switching, and (3) oscillation, all as part of circuits. A circuit consists of a series of connected electron devices and other parts. By combining the three functions in various ways, engineers design electronic equipment that performs many other special functions, such as the high-speed operations of […]
