Simple Circuit Builder vs Electronic Component Codes
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Simple Circuit Builder
This virtual lab offers a hands-on experience for learning about resistors and circuit resistance. Easily build and test series and parallel circuits, measure voltage and current, and understand the impact of component changes in real-time.
- Build circuits with up to eight components
- Five component types
- Virtual volt and amp meters
- Adjustable resistor and voltage values
- Real-time circuit analysis
- Demonstrates 'Opens' and 'Shorts'

Description This is the BEST app to learn about Resistors and Circuit Resistance (Equivalent Resistance). This virtual lab provides an excellent environment for anyone who is interested in understanding series and parallel resistors, learning how to measure voltages across resistors, current through series and parallel circuits and solving simple circuits. Features - VERY SIMPLE and EASY TO USE, with up to eight component sections. - Component sections can easily be configured from five different types. - VIRTUAL "Hands On" experience using volt and amp meters. - Resistor values can easily be changed with a picker, keypad or using randomize button. - Circuit voltage can easily be changed from 1 to 1000 volts with a picker or a keypad. - The "Basics" screen make this app unique for the simplicity and speed of seeing the effects of "Opens" (resistor component with infinite resistance) and "Shorts" (resistor component with zero resistance). - FREE and NO ADVERTISEMENTS. - The circuit is always "LIVE" and immediately shows voltage, current and circuit resistance with any changes made to the circuit.
