Simple Circuit Builder, Series Parallel Resistors

This is the BEST app to learn about Resistors and 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 be easily be changed from 1 to 1000 volts with a picker
or 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.
