Series and Parallel Circuit

As you continue to add lightbulbs in series, what happens?

• The bulbs get brighter

• The bulbs get dimmer

• The bulbs remain the same brightness

• The bulbs explode and shards of glass get everywhere

If one bulb goes out in a series circuit, the remaining bulbs...

• also go out

• get brighter

• get dimmer

• explode, leaving shards of glass everywhere

Current is measured in

• Volts

• Watts

• Seconds

• Amps

If the switch was opened, what would happen?

• the ammeter would measure a current flowing

• current would no longer flow, so everything would be off

• the bulbs would stay on because they're connected to the cell

• the bulbs would burn out and catch fire

The picture shows an electrical circuit. This circuit is a series circuit because: 

• It has 3 light bulbs.
• The same current flows through all three light bulbs.
• It uses a single battery.
• The electrical current is divided between the three light bulbs.

A material in which electrons are able to move easily

• Circuit
• Insulator 
• Resistance 
• Conductor 

This circuit has more than one loop. When one light goes out, the others stay on. 

• closed circuit
• series circuit
• parallel circuit
• open circuit

Which of these materials is a good insulator?

• Plastic and metal
• Metal and rubber
• Plastic and rubber

What is the energy source for a circuit?

• Light bulb
• Battery
• Wire
• Switch
