Electricity Test

What charge does an electron have?

• negative (-)
• positive (+)
• neutral or no charge (0)

Electric charges that are different _______ each other.

• Attract
• Repel

A region around a charged particle that can exert a force on another charged particle is called an

• electric pulse.
• electric charge.
• electric force.
• electric field.

Consider the electric field lines shown in the diagram below. From the diagram, it is apparent that object A is ____ and object B is ____.

• +,+
• +,-
• -,+
• -,-

Electrical charge built up on the surface of an object is called _________________.

• static electricity
• current electricity
• lightning
• electrons

the charging of an object by the contact of a charged object to a neutral object (like touching a door knob)

• induction

• conduction

• friction

Bending water with a charged balloon is an example of what type of charging (charging an object without touching)

• friction

• induction

• conduction

Electricity that flows in a closed path is called a

• path
• current
• circuit
• light

What is the major difference between static electricity and current electricity?

• Current electricity involves a continuous flow of elecrons; static electricity is a sudden transfer of protons

• Current electricity can be deadly; static electricity is almost always safe

• In current electricity, there's a single transfer of electrons; in static electricity, there's a steady flow of electrons

• Current electricity involves a flow of electrons; static electricity involves a single transfer of electrons

Materials that easily loose or accept electrons are considered

• Good conductors
• Good insulators
• Good anti-static agents
• Good for storing charge
