Circuit Review

What is a circuit?

• The path of magnetic fields

• The arrangement of batteries in a device

• The route electricity follows in loop

• The path of least resistance

How is a parallel circuit different from a series?

• It has multiple paths for the current to follow

• It has many branches that get weaker farther from the battery

• They are two circuits running side by side

• They are the same thing

What happens when you add a second bulb to a series circuit?

• The first bulb gets brighter

• The second bulb will be as bright as the first because they both get full power

• The circuit will no longer work

• Both bulbs will be half as bright because the voltage is divided

How can you tell this is a series circuit?

• Because there is only one path for electrons to travel

• Because there are multiple paths for electrons to travel

• Becasue it has a switch

• Becasue it the bulbs are equally bright

How can you tell what type of circuit this is?

• It's series becsaue the lights are the same brightness

• It's parallel because there are multiple pathways to the battery

• It's parallel becasue two lights are less bright than one light

• It's series becasue the bulbs are in order

What is resistance measured in?

• Ω (Ohms)

• V (Volts)

• A (Amps)

• W (Watts)

What are the two types of circuits called

• Linear & Parallel

• Series & Parallel

• Complete & Partial

• Series & Composite

What is a series circuit?

• The transfer of electrons from one object to another

• A circuit with a single path the current follows

• A circuit that goes in multiple directions

• A circuit that takes place in a series of events

Why are parallel circuits more commonly used in houses?

• Because they are faster than series

• Because if one light has a problem the rest will still work

• Because they are easier for electricians to wire

• Because they use less electricity

This picture is an example of what kind of circuit?

• Series

• Complete

• Broken

• Parallel
