About this app
When you do not have an exact resistor value in building a circuit, you need to combine two resistors either in series or in parallel. This app is used to find out all the combinations of these resistors making a desired resistance.
This app is suitable for hobbyist or electronic engineers.
Features:
1. Calculate resistance of 2 resistors in series / parallel (equivalent resistance)
2. To find out combinations of 2 resistors in series / in parallel making a desired resistance
3. Save all combinations in a CSV (Excel) file
Features in PRO version only:
1. No Ad
2. No limitation
Note :
1. For those who need support please email to the designated email.
Do NOT use either the feedback area to write questions, it is not appropriate and that is not guaranteed that can read them.

Very minimal option available, for all features we have to purchase. Then why ads in this version.
