In a test set up which was designed to obtain a zener-transistor regulated 4.8V supply at 5mA current: C ac =0.068µF, R1=10kO, R2=470O, R B =470O, C F =470µF, and Q1=BC549, with a 240V AC line. This ...

In contrast to alternating current, or AC, which, depending on the supply's frequency, switches direction 50 or 60 times per second, the current in DC circuits flows only in one direction.

AC and DC Current: AC (Alternating Current) and DC (Direct Current) are the two fundamental forms of electrical current, differing in how electricity flows through a circuit.

Power-supply circuit. A resonant-mode power-supply circuit is shown that uses the same electronic ballast IC to control an isolated LLC-type output stage. In this configuration, the output voltage is ...

If you have ever read advanced textbooks or papers about electronics, you may have been surprised to see the use of complex numbers used in the analysis of AC circuits. A complex number has two par… ...

If you got your start in electronics sometime after 1980 your first project might well have been to light up an LED. Microcontroller projects often light up an LED, too, and a blinking LED is somet… ...

Physicists have successfully generated an electrical current from the atomic motion of graphene, discovering a new source of clean, limitless power. Share: Facebook Twitter Pinterest LinkedIN Email ...

In the end, direct current gets you closer to the power source with higher efficiency than alternating current, but since our electrical demands tend to change, AC gives us the flexibility we need ...

When it comes to electrical circuits, there’s a lot to remember and understand. We've got you covered with this Intro to Circuits BBC Bitesize guide.

In contrast to alternating current, or AC, which, depending on the supply's frequency, switches direction 50 or 60 times per second, the current in DC circuits flows only in one direction.
