We can convert the High voltage AC into Low voltage DC without using the Transformer. This is known as Transformerless power supply. The main component of a Transformerless power supply is Voltage dropping capacitor or X-rated capacitor, which are specially designed for AC mains. This X rated capacitor is connected in series of Phase line of AC, to drop the voltage.

A potential divider circuit is a very common circuit used in electronics where an input voltage has to be converted to another voltage less than it. This circuit is very useful for all analog circuits where variable voltages are required, hence it is important to understand how this circuit works and how to calculate the values of Resistors.

This coil inductance calculator is designed to calculate the inductance of the coil, given the Relative permeability, No of turns, coil radius, and solenoid length.

We can calculate Current from Voltage, either by providing the Power or Resistance values.

The MB10F is a surface mount glass passivated bridge rectifier from diodes incorporated with a low voltage drop of 1.1V and a forward continuous current of 800mA. It has high efficiency and a high surge current capability of 30A.

Voltage doubler is the circuit where we get the twice of the input voltage, like if we supply 5v voltage, we will get 10 volt at the output. Generally transformers are there to step-up or step-down the voltage, but sometimes transformers are not feasible because of their size and cost. So here is the quick, easy and practical solution to double the voltage, using 555 timer IC.

Two HTML drop-down select boxes are used to select hour and minute values on a web page that are sent to an Arduino web server. The time values can be used to set a real-time clock or for any other time related settings.

The Li-ion 2 Cell Battery Charger Universal AC with wire is a lightweight and compact charging solution for 3.7V Li-ion batteries. Its universal AC input makes it convenient for use in different voltage standards across the world.
