In a series circuit, how many paths can current take?

• One

• Two

• Three

• Many

If one bulb breaks in a series circuit, what happens?

• The others stay on

• The circuit still works

• All bulbs go out

• Nothing changes

In a series circuit, the current is:

• Different in each part

• The same everywhere

• Zero

• Only at the battery

In a series circuit, the total voltage is:

• Shared between components

• The same across each component

• Zero

• Doubled
