Reed switch Working Principle
The reed switch is an electrical switch operated by an applied magnetic field. It was invented at Bell Telephone Laboratories in 1936 by W. B. Ellwood. It consists of a…
LC Tuned circuit Working Animation
Animated diagram showing the operation of a tuned circuit (LC circuit). This is an improvement over previous versions of this animation which uses variable frame display times to show…
Tap Changing Switch Animation
Animation of an on-load transformer tap changer, illustrating how taps can be selected without either interrupting supply or short-circuiting winding turns. The tap changer starts at tap position 2,…
Symmetric Three Phase Electric Current Flow Animation
Current flows from a three-phase generator on the left, represented as three Y-connected single-phase sources, via a transmission line into a symmetric Y-connected load on the right. The phases…
Three Way Electrical Switch Working Animation
Three Way Electrical Switch Alternative to the conventional connection for a three-way switch. The lamp shell is never connected to the live terminal. A second lamp can be connected at…
Electric Bell Working animation
Electric Bell  : How it works: 1. The button at the top (K) is closed. 2. Current flows through the solenoid (E). This produces a magnetic field. 3. This pulls…
PIN Diode Working Principle
The pin diode consists of heavily doped p and n regions separated by an intrinsic (i) region, as shown in Figure (a). When reverse-biased, the pin diode acts like a nearly…
