Circuits, Conductors, and Insulators

Front

What is a conductor?

Back

A material in which electrons can move easily, allowing electricity to flow. Examples include metals like copper and aluminum.

Front

What is an insulator?

Back

A material that does not allow electrons to move easily, preventing the flow of electricity. Examples include rubber, glass, and plastic.

Front

What is a closed circuit?

Back

A complete, connected circuit that allows electricity to flow. It has no breaks or gaps.

Front

What is an open circuit?

Back

A circuit that is not complete, meaning there is a break or gap that prevents electricity from flowing.

Front

What is resistance in a circuit?

Back

The opposition to the flow of electric current, measured in ohms. Higher resistance means less current flows.

Front

What are thermal conductors?

Back

Materials that allow heat to pass through easily. Examples include metals like copper and aluminum.

Front

What are thermal insulators?

Back

Materials that do not allow heat to pass through easily. Examples include wood, plastic, and rubber.

Front

Is water a conductor or an insulator?

Back

Water is a conductor, as it allows electricity to flow through it, especially when it contains impurities.

Front

What is the role of a switch in a circuit?

Back

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

Front

What is a battery?

Back

A device that stores chemical energy and converts it into electrical energy to power circuits.
