They will repel each other.
Socks taken from a clothes dryer that stick together or a lightning bolt in the sky are examples of ____________.
Static electricity
Is a circuit open or closed if you haven't turned on the switch?
It is an open switch.
What do you called a material that lets electric current pass through?
A conductor.
Electrons inside a battery flow from which terminal to which terminal?
From negative to positive terminal
If a south end of a magnet is close to a north end of a magnet, the magnets will _________.
Attract each other.
The invisible area or space surrounding a magnet where its magnetic force acts is called the ____________.
Magnetic field
What supplies current to an electrical circuit?
Battery/Power source
What is a material that blocks an electric current from passing through?
Insulator
When a proton enters a uniform magnetic field perpendicularly, the magnetic force acts as a centripetal force, forcing the proton into this specific geometric trajectory.
Circle/Circular path
If you rub your hair on a balloon and the balloon becomes negatively charged, what charge will your hair have?
What is a positive charge?
This safety device contains a thin metal strip that melts and breaks the circuit if the electrical current gets dangerously high.
A fuse
Electric utility companies use this non-SI unit to measure the total amount of electrical energy consumed by a household over time.
Kilowatt-hour/Kilowatt per hour (KWh or KW/h)
This SI unit is used to measure the strength and density of a magnetic field.
Tesla
It is the standard international unit of measurement for electrical potential, potential difference, and electromotive force.
Volts
This is the rate at which electrical energy is transferred or consumed in a circuit, mathematically expressed as P = IV.
Electrical Power
This type of modern safety switch automatically trips open using an electromagnet or bimetallic strip to shut off power during an overload condition.
A circuit breaker
This brilliant Scottish physicist synthesized electricity and magnetism into four definitive equations, predicting that light itself is an electromagnetic wave.
James Maxwell
An electromagnet must be part of an electrical ______.
Circuit
This fundamental law states that the current through a conductor between two points is directly proportional to the voltage across them.
Ohm's Law
This American statesman famously flew a kite in a thunderstorm to prove that lightning is a form of static electricity.
An electrical circuit is made up of a connector (wire), a load (lightbulb), a switch, and a ____________.
A batter/electrical source
This rule uses your right hand to determine the direction of a magnetic field around a straight, current-carrying wire by pointing your thumb in the direction of the current.
Right-hand rule
