What is the definition of current in electrical terms?

The definition of current in electrical terms refers to the flow of electrical charge through a conductor. This flow is typically measured in amperes (A) and represents how much charge is moving through the circuit per unit of time. Current is a fundamental concept in electricity that indicates the movement of electrons in a circuit, which is essential for powering devices and creating electrical energy. Understanding current is critical for fire investigators because electrical malfunctions can lead to fire hazards, making it important to grasp how electrical systems operate.

The other options describe different electrical concepts: voltage is associated with the pressure in an electrical circuit, resistance measures how much a material opposes the flow of current, and power relates to the total energy consumed by a device over time. Recognizing these distinctions helps in comprehensively understanding electrical systems and their potential hazards.
