Ohm Law
Read full descriptionHide full description
The invention of electricity is one of the greatest in human history, providing powerful mechanical energy, diverse communication and presentation methods, and intelligent information processing and control technologies. Ohm's Law and Kirchhoff's Voltage and Current Laws are fundamental, essential for beginners. This app demonstrates these laws, allowing users to connect batteries, bulbs, rheostats, ammeters, and voltmeters to observe current and voltage in series, parallel, and combined circuits. Suitable for students, electrical enthusiasts, physics lovers, and educators, it also offers leisure fun: watching old tungsten bulbs light up, feeling warm flickering light, measuring with traditional meters, and experimenting with shorts. Main features: 1. Batteries, bulbs, rheostats, and wires: Connect with red or black wires. Bulb brightness depends on current. 2. Voltmeter: Measures voltage across any circuit, with 3V and 15V ranges. 3. Ammeter: Measures current in series with any circuit, with 0.6A and 3A ranges. 4. Magnifier: Touch the screen (not rheostat slider) to zoom in on terminal positions or meter readings. 5. Circuit connections: Freely connect components in series, parallel, or combinations, following Ohm's and Kirchhoff's Laws. 6. Shorts: Overheated wires glow red in short circuits.

Verdict
The clearest difference is price: CUBE at Free against Ohm Law's $1.99. CUBE also leads on update cadence (weekly vs every 11 months) and iOS requirement (12.0 vs 15.6). On ads, in-app purchases and device support there is nothing between them.
