Basics of Electricity

The flow of electric charge is

• voltage

• current

• resistance

• electricity

A closed path that electric current flows is a

• circuit
• wire
• track
• hallway

Opposite charges ____________________.

• repel

• attract

When a switch is _________________, electric current can move through the circuit.

• off

• on

Like charges ______________________.

• repel

• attract

When the switch is ______________, there is no current running through the circuit.

• on

• off

In _________________________, the electrons flow in the same direction all of the time.

• alternating current

• direct current

A(n) _________________ from one atom can knock out an electron from another atom.

• battery

• voltage

• electron

• insulator

Copper is a good ______________________ which means that it is a material that allows electrons to flow well through it.

• insulator

• conductor

_____________________ is created as electrons collide and transfer from atom to atom.

• A conductor

• An insulator

• Electricity

• Voltage
