Ohm's Law

Scene Summary

In this sim, the Play Area contains the Ohm's Law equation, V equals I times R, and a circuit. There are also sliders to play with voltage and resistance. The circuit connects a resistor to a series of batteries. The circuit connects a resistor to a series of batteries. Batteries show amount of voltage. Dots in the resistor indicate the level of resistance in the resistor. In the Control Panel, buttons mute sound or reset sim.

Play Area

The Equation

Voltage, V, is equal to Current, I, times Resistance, R.

Letter V is [[much larger than]] letter I and [[comparable to]] letter R.

The Circuit

Connects a resistor to a series of batteries with a pair of wires.

Slider Controls

Voltage and resistance sliders allow changes to equation and circuit.
