3/1 quiz- circuit

What is a series circuit?

• A circuit with a single path the current follows

• The transfer of electrons from one object to another

• A circuit that takes place in a series of events

• A circuit that goes in multiple directions

How is a parallel circuit different from a series?

• They are the same thing

• It has multiple paths for the current to follow and the voltage stays the same in all lights

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

• They are two circuits running side by side

Why are parallel circuits more commonly used in houses?

• Because they are faster than series

• Because they use less electricity

• Because they are easier for electricians to wire

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

If the current through the battery was 10A in this diagram. What would the current through each bulb be?

• 20A

• 10A

• 5A

• 0A
