Chapter 6: Electricity

Front

What surrounds electric charge and exerts a force on other charges?

Back

Electric field: A region around a charged particle where a force would be exerted on other charges.

Front

What allows electrons to move through it easily?

Back

Conductor: A material that permits the flow of electric charge, typically metals like copper and aluminum.

Front

What is the push that causes charges to move?

Back

Voltage difference: The difference in electric potential between two points, which drives the flow of electric current.

Front

A metal rod that directs lightning directly to Earth is known as a what?

Back

Lightning rod: A device used to protect structures from lightning strikes by directing the electrical discharge safely to the ground.

Front

What is the flow of electrons through a conductor?

Back

Electric current: The continuous flow of electric charge, measured in amperes (A).

Front

What is the unit of electric current?

Back

Ampere (A): The unit of measurement for electric current, representing the flow of one coulomb of charge per second.

Front

What is the opposition to the flow of electric current?

Back

Resistance: A measure of the difficulty encountered by an electric current as it passes through a conductor, measured in ohms (Ω).

Front

What is the relationship between voltage, current, and resistance?

Back

Ohm's Law: V = I × R, where V is voltage, I is current, and R is resistance.

Front

What is a closed loop through which electric current can flow?

Back

Circuit: A complete path that allows electric current to flow, consisting of a power source, conductors, and a load.

Front

What is a device that converts electrical energy into mechanical energy?

Back

Motor: A machine that transforms electrical energy into mechanical motion.
