Description

From the listing uploaded by “retrodroidapps”.

The application is an easy-to-use color code calculator for calculating the resistance of a resistor. The application supports color codes for 4, 5, and 6-band resistors. Resistor A resistor is a component that is used in electrical circuits to limit the current flow. The resistance of a resistor is measured in Ohms (Ω). When a current (I) of one Ampère passes through a resistor with a voltage drop (U) of one Volt, the resistance of a resistor (R) corresponds with one Ohm. This ratio is represented by Ohm's law: R = U ÷ I. Color code The color codes on a resistor identifies the resistance, tolerance, and/or temperature coefficient of a resistor. Resistors come in variation with 4, 5, or 6 colors bands, as shown in the logo of this application. In the following, the meaning of each band is described for each type of resistor. 4-band resistor 1. The first band represents the first digit of the resistance value. 2. The second band represents the second digit of the resistance value. 3. The third band represents the multiplication factor of the resistance value. 4. The fourth band represents the tolerance in percentage of the resistance value. 5-band resistor 1. The first band represents the first digit of the resistance value. 2. The second band represents the second digit of the resistance value. 3. The third band represents the third digit of the resistance value. 4. The fourth band represents the multiplication factor of the resistance value. 5. The fifth band represents the tolerance in percentage of the resistance value. 6-band resistor 1. The first band represents the first digit of the resistance value. 2. The second band represents the second digit of the resistance value. 3. The third band represents the third digit of the resistance value. 4. The fourth band represents the multiplication factor of the resistance value. 5. The fifth band represents the tolerance in percentage of the resistance value. 6. The sixth band represents the temperature coefficient of the resistance value. In total, there are 12 different colors. The colors are black, brown, red, orange, yellow, green, blue, violet, grey, white, gold, and silver. The resistance of the resistor is determined by the colors of the bands.

Resistor Color Code Calculator APK: questions and answers

Can I install this APK over the version I already have?

Only if it is signed with the same certificate as the copy on your phone and isn't an older version. If Android says “App not installed”, the certificates differ; uninstalling your copy first works but deletes its data unless it is backed up.

Is Resistor Color Code Calculator free?

The APK is free to download, but the app offers in-app purchases through Google Play.

Is the Resistor Color Code Calculator APK safe?

No one can promise that a file is safe, but some things can be checked. The source store rates this file Trusted. After downloading, check that the file's MD5 is 42d3b1ced4026a1c962bd2b6970baf25.
