Electric Circuits

Front

What is an electric circuit?

Back

An electric 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 current flows through each component one after the other. In a parallel circuit, components are connected across common points, allowing current to flow through multiple paths.

Front

What happens when a circuit is open?

Back

When a circuit is open, there is a break in the path, preventing electric current from flowing, which means devices like light bulbs will not work.

Front

What is the role of a battery in a circuit?

Back

A battery provides the electrical energy needed to push electric charges through the circuit.

Front

What is a conductor?

Back

A conductor is a material that allows electric charges to flow easily, such as copper or aluminum.

Front

What is an insulator?

Back

An insulator is a material that resists the flow of electric current, such as rubber or glass.

Front

What is the function of a switch in a circuit?

Back

A switch controls the flow of current in a circuit by opening (turning off) or closing (turning on) the circuit.

Front

Why is copper commonly used in electrical wiring?

Back

Copper is used in electrical wiring because it is an excellent conductor of electricity, allowing efficient current flow.

Front

What is voltage?

Back

Voltage is the electrical potential difference between two points in a circuit, which drives the flow of current.

Front

What is current?

Back

Current is the flow of electric charge in a circuit, measured in amperes (A).
