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…
Power Supply Circuit Fault Analysis
In some cases, after isolating a fault to a particular circuit, it may be necessary to isolate the problem to a single component in the circuit. In this event, you have…
Tunnel Diode Working Principle
A tunnel diode or Esaki diode is a type of semiconductor that is capable of very fast operation, well into the microwave frequencyregion, made possible by the use of the…
