QuestionAnswer What is the basic unit of electric current? The basic unit of electric current is the ampere (A). How does a simple circuit work? A simple circuit works by allowing electric current to flow from a power source through conductors and components, completing a loop. What is the function of a resistor in an electrical circuit? A resistor limits the flow of electric current and can be used to control voltage and current levels within a circuit. 5 What is the difference between series and parallel circuits? In a series circuit, components are connected end-to- end in a single path, while in a parallel circuit, components are connected across the same two points, providing multiple paths for current. What safety precautions should you take when working with electricity? Always switch off power before working on circuits, avoid water contact, use insulated tools, and never touch live wires. Why do some materials conduct electricity while others do not? Materials that conduct electricity, like metals, have free electrons that allow charge to flow easily, while insulators lack free electrons and resist electrical flow.
