What is a closed circuit?

Back

A closed circuit is a complete electrical loop that allows electricity to flow through it, enabling devices like bulbs to work.

Front

What is an open circuit?

Back

An open circuit is a broken electrical loop where electricity cannot flow, preventing devices from functioning.

Front

What is an electromagnet?

Back

An electromagnet is a type of magnet that is created by electric current flowing through a coil of wire, often wrapped around a ferromagnetic core.

Front

How can you increase the strength of an electromagnet?

Back

You can increase the strength of an electromagnet by adding more coils of wire, increasing the electric current, or using a stronger core material.

What is electricity?

Back

Electricity is the flow of electric charge, primarily carried by electrons, through a conductor.

Front

What is a battery?

Back

A battery is a device that stores chemical energy and converts it into electrical energy to power electrical devices.

Front

What is a conductor?

Back

A conductor is a material that allows electricity to flow through it easily, such as copper or aluminum.

Front

What is an insulator?

Back

An insulator is a material that resists the flow of electricity, preventing current from passing through, such as rubber or glass.

What happens if one bulb in a series circuit goes out?

Back

If one bulb in a series circuit goes out, all the bulbs will stop working because the circuit is broken.

Front

What happens if one bulb in a parallel circuit goes out?

Back

If one bulb in a parallel circuit goes out, the other bulbs will continue to work because each bulb has its own separate path for electricity.
