Electricity

What charge does a proton have?

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

What charge does an electron have?

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

True or False
Like charges repel

• True
• False

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

• Current electricity involves a continuous flow of neutrons; 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
