Ohm's Law
This interactive simulator explores Ohm's Law in Electricity & Magnetism. Adjust voltage and resistance. See current change with interactive V-I graph. Use the controls to change the scenario; watch the visualization and any graphs or readouts to connect the model with lectures, labs, and homework.
Who it's for: Suited to beginners and first exposure to the topic. Typical context: Electricity & Magnetism.

How it works
Ohm’s law: for many metallic conductors at constant temperature, current through a resistor is proportional to the voltage across it, I = V/R. The V–I curve is a straight line through the origin; its slope is the conductance 1/R.
