In today’s world showing numbers and letters on multiple LED displays is pretty simple, thanks to microcontrollers like Arduino or Raspberry Pi. With just a small piece of code we can easily display the digits we need. But as electronics students or hobbyists there are times when we need to show multiple numbers or digits […]

Explained: How Asynchronous Counter Works
An asynchronous counter is really cool because it can handle a total of 2n-1 different counting states. For example a 4-bit counter set up as MOD-16 can count from 0 all the way to 15, making it great for things like frequency division. But you can also use the basic design of an asynchronous counter […]
Transformer Voltage Regulation: Explained with Formulas
When we talk about voltage regulation we are looking at how good a transformer is at keeping its secondary voltage steady even when the load changes. Sometimes the output voltage we get from the secondary side is not exactly what we were expecting and that is where voltage regulation comes into play. Now when you […]
Explained: Three Phase Transformers and Calculations
A 3-Phase electricity is basically a method we use to create and send electric power over really long distances so that our offices and industries can use it. In this setup we deal with three-phase voltages and currents which we can adjust either increase or decrease, using three-phase transformers. These transformers are pretty cool because […]
Current Transformer Explained with Calculations
We use a Current Transformer (C.T.) as an “instrument transformer.” It creates an alternating current in its secondary winding that matches the current in its primary winding. Current transformers lower high voltage currents to safer levels. They help us monitor the actual electrical current in an AC transmission line using a standard ammeter. The way […]
Autotransformer Working and Calculations Explained
An autotransformer is not like the traditional voltage transformer. Normally a voltage transformer has two distinct windings. These windings are called the primary and the secondary. But with an autotransformer things are a bit different because it only has one single winding that actually does the job of both the primary and the secondary. Now […]
