AAP Electricity and Magnetism

Front

What is a closed circuit?

Back

A closed circuit is a complete electrical loop that allows current to flow. All components are connected, and the circuit is unbroken.

Front

What is an open circuit?

Back

An open circuit is a broken electrical loop where current cannot flow. This occurs when a switch is turned off or a component is removed.

Front

What is a series circuit?

Back

A series circuit is a type of electrical circuit in which components are connected end-to-end, so the same current flows through all components.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of electrical circuit where components are connected across common points, allowing multiple paths for current to flow.

Front

What is a conductor?

Back

A conductor is a material that allows electric current to flow easily, such as metals like copper and aluminum.

Front

What is an insulator?

Back

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

Front

What is an electromagnetic wave?

Back

An electromagnetic wave is a wave of energy that is propagated through space by oscillating electric and magnetic fields.

Front

What is a changing electric field?

Back

A changing electric field is an electric field that varies with time, which can induce a magnetic field and is essential for creating electromagnetic waves.

Front

What happens to the current in a series circuit if one component fails?

Back

If one component fails in a series circuit, the entire circuit is broken, and all components stop working.

Front

What happens to the current in a parallel circuit if one component fails?

Back

If one component fails in a parallel circuit, the current can still flow through the other paths, so the remaining components continue to work.
