Electricity Basics

The flow of electric charges is

• voltage

• current

• resistance

• electricity

A closed path that electric current flows is a

• circuit
• wire
• track
• hallway

What is the unit of measurement for current?

• Amperes

• Ohm's

• Volts

• Watts

In our circuit builds, a ________________________provides the voltage to push current through the circuit.

• switch

• battery

• resistor

• wire

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

How do wires work?

• they become an electrical charge
• they bend electricity easily
• they keep the charge from moving randomly
• they allow a current of electricity to flow 

What is the main purpose of a battery?

• to pump electricity through the wires
• to make things go
• to provide just the right amount of energy needed
• to replace household electricity
