Circuits Quiz Practice

What 2 things do you need for a complete circuit?

• A lightbulb

• A Power Source

• A complete conducting loop

• A switch

• A Resistor

What type of circuit is this?

• Parallel

• Series

Parallel circuits...

• Have multiple pathways for electrons

• Have higher current than series circuits

• Have brighter bulbs than series circuits

• All of the above

• None of the above

What is this a picture of?

• A parallel circuit with 2 bulbs and 2 batteries

• A series circuit with 2 bulbs and 2 batteries

• A parallel circuit with 3 bulbs and 2 batteries

• A series circuit with 3 bulbs and 2 batteries

• A series circuit with 3 bulbs and 1 battery

Let's say you have a series circuit with 3 lightbulbs and one 3 volt battery. ABOUT how many volts would each bulb get?

• About 1 volt each

• About 3 volts each

• About 1.5 volts each

• About 6 volts each

Let's say you have a parallel circuit with 3 bulbs and one 3 volt battery. ABOUT how many volts would each bulb get?

• 1 volt each

• 3 volts each

• 1.5 volts each

• 6 volts each

What would happen in a SERIES circuit if you unscrewed one of the lightbulbs from its base?

• The current would go up

• The circuit would break and the other lights would go out

• Nothing would happen, there are other places for the electrons to go

• The voltage in the battery would increase

What would happen if you unscrewed a lightbulb in a PARALLEL circuit from its base?

• The current would go up

• There would be a break in the circuit, and the other lights would go out

• Nothing would happen, there are other pathways for the electrons to travel

• The voltage in the battery would go up

What are some major differences between parallel and series circuits?
