The current-voltage relationship, often described by Ohm's Law, states that the current through a conductor between two points is directly proportional to the voltage across the two points, provided the temperature remains constant. This fundamental principle is crucial for understanding and designing electrical circuits, as it helps predict how changes in voltage will affect the current flow in a circuit.

current-voltage relationship

Ohm's Law is a fundamental principle in electronics and electrical engineering that states the current through a conductor between two points is directly proportional to the voltage across the two points, provided the temperature remains constant. This relationship is mathematically expressed as V = IR, where V is voltage, I is current, and R is resistance.

Understanding electrical circuits

Designing electrical circuits is like creating a path for electricity to travel, just like building a road for cars. It helps lights turn on, toys move, and makes all the things we use every day work properly.
