🔌 Ohm's Law Circuit

📖 The Physics

Ohm's law is the most-used rule in electricity: the current through a conductor equals the voltage across it divided by its resistance. Think of voltage as the push and resistance as how much the wire holds the flow back.

More voltage pushes more current through; more resistance lets less through. Watch the blue charges speed up as the current rises.

Raise the voltage and the current increases in proportion. Raise the resistance and the current drops. The flowing dots move faster when the current is larger.
