Electrical Current: The Flow of Charge
At its core, electrical current is the flow of electric charge. Think of it like water flowing through a pipe; the more water passes through a point in a given time, the higher the flow rate. Similarly, in electrical circuits, the more charge that flows, the greater the current. Current is measured in amperes (A), which is defined as the flow of one coulomb of charge per second. So, when we say a device has a current of 15.0 A, it means 15 coulombs of charge are flowing through it every second. Understanding this concept is crucial. Electrical current is the movement of electrically charged particles in a circuit. These particles are typically electrons, which carry a negative charge, flowing through a conductive material, like a copper wire. The flow is driven by a voltage difference, similar to how water flows from a higher to a lower elevation. The magnitude of the current is determined by how much charge passes a given point in the circuit per unit of time.
