Static Electricity

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

• static electricity
• current electricity
• lightning
• electrons

• proton

• neutron

• electron

If a substance has a higher number of electrons than protons on its surface, what type of charge does it have?

• A positive charge.
• A negative charge.
• A neutral charge
• No charge at all

An object that is neutral contains the same number of electrons and protons.

• True

• False

What types of charges attract?

• Positive and Positive
• Positive and Neutral
• Negative and Neutral
• Positive and Negative

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
