Ohm's Law

Scene Summary

In this sim, there are sliders in the Play Area to simultaneously explore two representations of Ohm's Law:

  1. the equation, V equals I times R, and
  2. a circuit, two wires connecting a series of batteries to a resistor.

Buttons in the Control Panel mute sound and reset sim.

Right now,

Thus,

Look sliders to play.

Play Area

In Equation

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

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

In Circuit

Slider Controls

Voltage and resistance sliders allow changes to equation and circuit.
