Circuits, Conductors, and Insulators

Front

What is a conductor?

Back

A material in which electrons are able to move easily, allowing electric current to flow.

Front

What is an insulator?

Back

A material that does not allow electrons to move freely, preventing electric current from flowing.

Front

Define a complete circuit.

Back

A complete circuit, or closed circuit, is a path through which electricity can flow without interruption.

Front

What is an open circuit?

Back

An open circuit is an incomplete or broken circuit where electricity cannot flow.

Front

What is the role of a battery in a circuit?

Back

A battery provides the necessary voltage to push electric current through the circuit.

Front

What happens when a circuit is open?

Back

When a circuit is open, the flow of electricity is interrupted, and devices connected to the circuit will not operate.

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 resistance in a circuit?

Back

Resistance is a measure of the opposition to the flow of electric current, typically measured in ohms.

Front

What materials are typically used as conductors?

Back

Common conductors include metals such as copper, aluminum, and silver.

Front

What materials are typically used as insulators?

Back

Common insulators include rubber, glass, and plastic.
