Basic Power Supply block Diagram (AC – DC convertion process)

Power Supply block Diagram

Many electronic circuits need a direct current (DC) voltage source, but what we commonly find are voltage sources of alternating current (AC). In order to achieve a direct current voltage source, the alternating current input must follow a convertion process.

What are Microwaves? Applications, Frequency & Wavelength

What are Microwaves? Applications, Frequency & Wavelength

Microwaves

At the present time the radio frequency spectrum is becoming small for the growing demand for telecommunications. The incursion into the field of microwaves is natural and we must also take into account that there are some applications that are unique to the microwave frequencies.

Capacitor and Direct Current (DC) - Dielectric

Capacitor and Direct Current (DC) – Dielectric

Capacitor and Direct Current

If a battery is connected to a capacitor, it will allows no direct current (DC) to flow through. If a not charged capacitor is connected across the terminals of a battery, a transient current flows as the capacitor plates charge up.

Capacitor and Direct Current. Current starts from its maximum value and decreases to 0 amps. This current is called “transient current”.
