## Voltage Divider Calculator

https://circuitdigest.com

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.

## Voltage Doubler Circuit

http://circuitdigest.com

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.

## UNDERSTANDING CURRENT, VOLTAGE AND POWER

http://www.smps.us

The purpose of electronic circuits is to control the flow of electric currents. This may sound like a silly question, but why do we need to control the currents? Well, it has been found experimentally that the intensity of various electrical effects is related to the amount of the charge Q that passes by a certain region per unit time.

## Voltage Controlled Pulse Width Oscillator

http://home.cogeco.ca

The basic circuit operates at a frequency determined by R1, R2 and C1 and has a pulse width range of 0 to 100 percent.

The following diagram shows a basic circuit with an open collector output that would require a pull up resistor at its output. The parts values are the nominal values of the components used.
