What is static electricity?

Back

Static electricity is a buildup of electric charge on the surface of objects, often caused by friction. It can cause a shock when you touch a conductive material after walking on a carpet.

Front

What is an insulator?

Back

An insulator is a material that does not allow electrons to move easily through it. Examples include rubber, glass, and wood.

Front

What type of charge does a neutral object have?

Back

A neutral object has no overall electric charge; it has an equal number of positive and negative charges.

Front

What is current electricity?

Back

Current electricity is the flow of electric charge through a conductor, such as a wire, and is used to power devices like light bulbs and cell phones.

Front

What is static electricity often associated with?

Back

Static electricity is often associated with sudden bursts of electricity, such as when you touch a metal doorknob after walking on a carpet.

Front

What happens when you rub a balloon on your hair?

Back

Rubbing a balloon on your hair transfers electrons, giving the balloon a negative charge and your hair a positive charge.

Front

What is a conductor?

Back

A conductor is a material that allows electrons to move freely through it. Examples include metals like copper and aluminum.

Front

What is resistance in an electrical context?

Back

Resistance is a measure of how much a material opposes the flow of electric current. Higher resistance means less current can flow.

Front

What is the role of a circuit in electricity?

Back

A circuit is a closed loop that allows electric current to flow. It typically includes a power source, conductors, and a load (like a light bulb).

Front

What is the difference between static and current electricity?

Back

Static electricity is a stationary charge that builds up on surfaces, while current electricity is the continuous flow of electric charge through a conductor.
