What is electrical current?
Electrical current is the movement of electric charge, carried by electrons, through a conductor. It can be visualized as the water flowing through a pipe, where the water represents the electrons and the pipe means the conductor.
Voltage causes an electric current to flow via a circuit, often called the electric potential difference. The potential energy per unit charge is represented by this number, which is measured in volts (V). It is possible to think of voltage as the pressure that forces electrons to travel.
Particles with a negative charge called electrons revolve around an atom’s nucleus. The outermost electrons are loosely bound and can move in conductive materials like metals. When a voltage is applied across a conductor, these electrons flow in response to the electric field, creating an electric current.
What is DC current? DC, or direct current, is a type of electrical current that flows in a single direction. Unlike alternating current (AC), which changes direction, DC maintains a constant flow. “To ensure safety, testing outlet polarity with a multimeter is crucial.”
