Description This app is a virtual "Bread Board" of configurable resistors. It also includes a virtual volt and amp meter. 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 or using randomize button. - Circuit voltage can easily be changed from 1 to 250 volts with a picker. - The Randomize function provides a great way to reinforce your knowledge. - FREE and NO ADVERTISEMENTS. - The circuit is always "LIVE" and immediately shows voltage, current and circuit resistance with any changes made to the circuit.
