Electricity

The charge on a proton is

• negative

• positive

• neutral

The buildup of charges on an object is called

• static discharge

• static electricity

• positive charge

• negative charge

According to Ohm’s law, resistance is equal to voltage divided by

• time

• conduction

• current

• potential

A complete, unbroken path through which electric charges can flow is a(n)

• electric circuit

• electrical resistance

• magnetic field line

• magnetic pole

Materials through which charge can flow easily are called

• insulators

• conductors

• resistors

• magnets

An example of an insulator is

• rubber

• copper

• silver

• iron

The ampere is a unit of

• magnetism

• electric current

• electric charge

• temperature

Electric charges that are different

• attract each other.

• repel each other.

• exist in pairs.

• do not interact.

The loss of static electricity as electric charges transfer from one object to another is called

• friction

• conduction

• induction

• static discharge

A device used to open and close an electric circuit is a(n)

• light bulb

• energy source

• switch

• resistor
