FAQs on What is an Electric Circuit? Video Lecture - Science Class 7

1. What is an electric circuit?

Ans. An electric circuit is a closed loop that allows electric current to flow through it. It consists of various components such as a power source (like a battery), conductors (wires), and loads (devices like bulbs or motors) that use the electrical energy.

2. What are the main components of an electric circuit?

Ans. The main components of an electric circuit include a power source (such as a battery or power supply), conductors (wires that connect the components), a load (like a resistor, bulb, or motor that consumes electricity), and switches (to control the flow of current).

3. What is the difference between a series and parallel circuit?

Ans. In a series circuit, all components are connected end-to-end, so the same current flows through each component. In contrast, in a parallel circuit, the components are connected across common points, allowing current to split and flow through multiple paths simultaneously.

4. How does current flow in an electric circuit?

Ans. Current flows in an electric circuit from the positive terminal of the power source, through the conductors, into the load, and then back to the negative terminal of the power source. This flow of electric charge is driven by the voltage provided by the power source.

5. What are some common applications of electric circuits?

Ans. Common applications of electric circuits include household wiring systems, electronic devices (like smartphones and computers), automotive electrical systems, lighting systems, and various industrial automation and control systems.
