V-I Relationship

Circuit Diagram

Ohm's Law: Current through a conductor is directly proportional to voltage and inversely proportional to resistance. In a series circuit: same current flows through all resistors, voltages add up. In a parallel circuit: same voltage across all resistors, currents add up. Animated dots represent electron flow — faster dots = higher current.
