What is an electrical circuit?

Back

An electrical circuit is a closed loop that allows electric current to flow, consisting of a power source, conductors, and a load.

Front

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

Back

In a series circuit, components are connected end-to-end, so the same current flows through all components. In a parallel circuit, components are connected across common points, allowing multiple paths for current.

Front

What is an electrical insulator?

Back

An electrical insulator is a material that does not allow electricity to pass through it, preventing the flow of electric current.

Front

What is the purpose of using a plastic covering on electrical wires?

Back

The plastic covering on electrical wires serves as insulation, making it safe by preventing accidental contact with the conductive wire.

Front

What happens in an open circuit?

Back

In an open circuit, there is a break in the path, preventing electric current from flowing, which means the circuit will not work.

Front

What is the role of a power source in an electrical circuit?

Back

The power source provides the electrical energy needed to drive the current through the circuit.

Front

What is a load in an electrical circuit?

Back

A load is any component in a circuit that consumes electrical energy, such as a light bulb or resistor.

Front

How can you identify a series circuit from a diagram?

Back

A series circuit can be identified by a single path for current flow, where all components are connected in a line.

Front

What is the function of a switch in an electrical circuit?

Back

A switch controls the flow of current in a circuit by opening (breaking the circuit) or closing (completing the circuit) the path.

Front

What is the significance of circuit diagrams?

Back

Circuit diagrams provide a visual representation of an electrical circuit, showing how components are connected and the flow of current.
