This app invites to explorations into electricity and the serial circuit. You can freely explore a simulated serial circuit in order to find out electricity facts. The simulation not only reflects real circuit behaviour, but also provides insights into electron flow that real experiments cannot provide. "Wrong" usage can be tried out without fear of destroying components while clearly warning about potential destroyment. Experimentation is guided by the following booklets provided gerin the app: - Knowledge: learn facts about the circuit - Puzzles: solve puzzles on levels from beginner to expert - Experiments: explore unusual situations - Tricks: achieve surprising results The booklets provide helpful hints if tasks cannot be solved on their own. The app greatly supports class room learning as well as self motivated learning and explorations.

Verdict
The clearest difference is price: Impedance Calculators at Free against Voltages S's $0.99. Voltages S's advantage is in-app purchases (none vs 1) and ads (none vs shown). On device support and iOS requirement there is nothing between them.
