Electricity

Front

What is an insulator in the context of electricity?

Back

An insulator is a material that does not allow electricity to flow through it easily, preventing the flow of electric current.

Front

What does it mean if a circuit is closed?

Back

A closed circuit is one where the electrical path is complete, allowing current to flow and devices like light bulbs to operate.

Front

What is a series circuit?

Back

A series circuit is a type of electrical circuit that has only one path for the electric current to flow.

Front

Can you give an example of static electricity?

Back

An example of static electricity is when a boy shocks his sister after sliding his feet across the carpet.

Front

What is a power source in an electric circuit?

Back

A power source is a device that supplies electrical energy to a circuit, such as a battery or a generator.

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 the difference between static electricity and current electricity?

Back

Static electricity is the buildup of electric charge on the surface of objects, while current electricity is the flow of electric charge through a conductor.

Front

What is Ohm's Law?

Back

Ohm's Law states that the current (I) through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R) of the conductor, expressed as V = I * R.

Front

What is resistance in an electrical circuit?

Back

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

Front

What is the role of a switch in an electric circuit?

Back

A switch is a device that can open or close a circuit, controlling the flow of electricity.
