FAQs on Electricity and Circuits - 2 Video Lecture - Living Science (Ratna Sagar) for Class 6

1. What is an electric circuit?
Ans. An electric circuit is a closed path through which electric current flows. It typically consists of a power source (like a battery), conductors (wires), and a load (such as a light bulb or motor) that uses the electricity. Without a complete loop, the current cannot flow, and the circuit is considered open.
2. What are the main components of a simple electric circuit?
Ans. The main components of a simple electric circuit include a power source (like a battery), conductors (wires), a load (such as a light bulb), and a switch. The power source provides the energy, the conductors allow the flow of electricity, the load uses the electricity, and the switch can open or close the circuit.
3. How does a series circuit differ from a parallel circuit?
Ans. In a series circuit, all components are connected in a single path, so the same current flows through each component. If one component fails, the entire circuit stops working. In contrast, a parallel circuit has multiple paths for current to flow. If one component fails, the other components can still operate because they have alternative paths for the current.
4. What safety measures should be taken when working with electricity?
Ans. When working with electricity, some important safety measures include wearing rubber-soled shoes, avoiding wet areas, using insulated tools, ensuring that hands are dry, and never touching electrical appliances with wet hands. It’s also important to turn off the power supply before working on electrical circuits and to use circuit breakers or fuses to prevent overloads.
5. What is static electricity and how does it differ from current electricity?
Ans. Static electricity is the buildup of electric charge on the surface of objects, usually caused by friction. It can result in sparks or shocks when the stored charge is discharged. Current electricity, on the other hand, is the flow of electric charge through a conductor, like wires, and is what powers electrical devices. Static electricity is a temporary condition, while current electricity is a continuous flow.
