Houses, schools, and other buildings are wired using parallel circuits.

• True

• False

One example of a good conductor is ____.

• copper

• glass

• wood

• Rubber

Which of the following is a device designed to open an overloaded circuit (stops the flow of electricity) and prevent overheating?

• circuit breaker

• resistor

• conductor

• Insulator

Copper is used in household wiring because ____.

• it is a good insulator and therefore allows little current to flow through it

• it produces a rainbow when current passes through it

• it produces heat in the wires when current passes through it

Resistance is measured in a unit called the ____.

• ampere

• ohm

• watt

• Volt

A circuit that has two or more separate paths for electrons to follow is a(n)____.

• circuit breaker

• parallel circuit

• electron circuit

• series circuit

A path created for a current that allows only one route for the current is called a ____.

• parallel circuit

• series circuit

• parallel current

• series current

A series circuit has more than one path for the electric current to follow.

• True

• False

Which of the following has the least resistance?

• a long, narrow metal wire

• a short, thick metal wire

A material through which electrons DO NOT easily flow is a(n)____.
