This is a great multipurpose resistors calculator! This application is a must-have for students or hobbyists. Not only does it give you the information you need, but it provides intermediate information to help students understand how the processes work. Multiple screens allow you to perform various calculations related to resistors.

Ohm's Law screen allows you to calculate resistance, voltage, current, and power given any two. This easy to use interface allows you to quickly calculate the value you need. It also features capability to lock down an input value.

Circuit screen allows you to build your own circuit of resistors. As you are building the circuit of resistors in any configuration of series and parallel it presents you instantly with the overall resistance and selected region resistance. In-app purchase upgrade allows this screen to handle an unlimited number of resistors.

Color screen is great for determining resistance using the color bands on resistors. Simply scroll to the color of each band and you are shown the resistance and tolerance of your resistor. Great for finding out what resistance a given resistor is without having to go find a table of color values. Works for both 4 band and 5 band resistors.
