Simple Circuit Builder is the BEST app for anyone interested in understanding resistors and equivalent resistance. This virtual lab provides an excellent environment to learn about series and parallel resistors, measure voltages across resistors, analyze current in series and parallel circuits, and solve simple circuits.

The app is VERY SIMPLE and EASY TO USE, with up to eight component sections that can be easily configured from five different types. It offers a VIRTUAL "Hands On" experience using volt and amp meters, allowing users to interact with the circuit components.

One of the standout features is the ability to easily change resistor values using a picker, keypad, or the randomize button. Additionally, the circuit voltage can be adjusted from 1 to 1000 volts with a picker or a keypad.

What sets Simple Circuit Builder apart is its "Basics" screen, which allows users to quickly see the effects of "Opens" (resistor component with infinite resistance) and "Shorts" (resistor component with zero resistance). This feature makes the app unique in terms of simplicity and speed.

The best part? Simple Circuit Builder is completely FREE and has NO ADVERTISEMENTS. The circuit is always "LIVE" and immediately shows voltage, current, and circuit resistance with any changes made to the circuit.

Whether you're a beginner or an experienced learner, Simple Circuit Builder is a must-have app to deepen your understanding of resistors and equivalent resistance.
