## CapCalC

This app is simple to calculate the life of an aluminum electrolytic capacitor. I have to design engineers and electronics, students to study the electronic circuit, the app to turn on your computer, such as nerd, easy to implement simple.

■ How to use

Indeed, by operating the electrolytic capacitor life you wish, we measure the temperature of the surface (the upper surface of the metal part).

• Enter into this application of the measured surface temperature, temperature rating of electrolytic capacitors, the rated life.

■ How to operate

Rated life of an electrolytic capacitor, (h)

· Rated temperature (℃)

Surface temperature (℃)

Enter the Press "to display the next screen" results

The calculated lifetime is displayed.

※ The calculation has been using a formula that uses the property of the capacity is reduced in speed 10 ℃ 2 the Arrhenius equation, is due to the simplified calculation only, strictly considered acceleration factor ripple, ripple current you need to. It is not a guaranteed value is the value calculated by this app, do not trust the calculated value may also in any application.

※ Since the sealing rubber and lifetime degradation in 10-15 years even if the calculated value is more than 10 years, please think about 10 years.

※ ripple current of the capacitor are with rated ripple current.

## Electronics Helper

This application i.e."Electronics Helper" is basically developed for the electronics students and associated people of this field to help them in understanding the basics and simplifying the various complex calculations which are more often than not associated with it.

The purpose of developing this app is to provide ease to the users while doing tedious and complex calculations of electronics. Almost all electronics calculations can be performed by it(for instance,this app includes basic "ohm's law calculator" to "resistor and capacitor series/parallel calculator", "555 timer generator calculator" to "electricity and energy consumption calculator",and many more). Overall 14 sub apps are inside it. Moreover it has more than 35 calculators inside a single sub app i.e. "electrical calculator" (which is one out of the 14 sub app of this main app).

It also includes "resistor color code calculator app" along with almost all transistors and diodes series specifications.

By and large, it has included all the electronics calculator apps inside a single app which will certainly help the users in solving their related problems.

## Timer IC 555 Tool

The app tries to be a reference of LM555 for students, teachers and hobbyists of electronic.

You can calculate time for monostable mode, frequency and duty cycle for astable mode. The advantage of this app is you can decide if you start with capacitor, resistor or frequency. You can learn about block diagram, functions, operations mode and a wiring option on protoboard.

Also, the tool has a amazing feature to plot the behavior between a range selected.

Additional that is possible to share or save your calculations in your device.

## Capacitor Charge Formula

This app calculates all the variables from the capacitor charging voltage equation { Vc=Vs*[1-e^( -t/(r*C) ) ] } and there is the possibility to insert or to get the solution in different scale units (such as milli, Kilo etc.). Also, it includes a PDF file with the proof of the formula that is used for the calculations in the app. Finally, If you find a bug or you want to suggest a feature send me an email at: iron.electronics@gmail.com
