Electricity: Intro

A material that does NOT let electricity pass through it is called ...

• An electrical conductor

• An electrical insulator

• An electrical source

• An electric appliance

What is a circuit with several paths for electricity to flow?

• conductor

• series circuit

• parallel circuit

• open circuit

What is a circuit that only has ONE path for electricity to flow?

• series circuit

• closed circuit

• parallel circuit

• light bulb

An incomplete circuit is shown.
To complete the circuit, a wire should be placed from —

• Point D to Point C
• Point B to Point C
• Point A to Point D
• Point B to Point D

The force that pushes the electricity through a circuit is called...

• resistance
• voltage
• current
• switch

The flow of electricity through a conductor is called...

• resistance
• voltage
• current
• source of electric current

What slows down the flow of electricity in a circuit?

• resistance
• voltage
• current
• source of electric current

Which circuit (s) are parallel?

• A
• A and B
• B and C
• C

If I add more light bulbs to a series circuit what happens?

• The current speeds up and the lights get brighter
• The current slows down and the lights dim lower
• The current speeds up and the lights dim lower
