Definition
The fundamental concepts in electrical engineering that describe the flow of electric charge, including the differences between voltage, current, and their applications in various electrical systems
Summary
Electric voltage and current are fundamental concepts in electricity. Voltage, measured in volts, is the potential difference that drives electric charge through a circuit, while current, measured in amperes, is the actual flow of that charge. Understanding these concepts is crucial for working with electrical devices and circuits, as they determine how electricity behaves in various applications. Ohm's Law provides a vital relationship between voltage, current, and resistance, allowing us to calculate how much current will flow in a circuit based on the voltage applied and the resistance present. By grasping these principles, learners can better understand the workings of everyday electrical devices, from batteries to household appliances.
