What happens in a series circuit if one bulb breaks?

• All the other bulbs stay on.

• The current increases.

• All the other bulbs go off.

• The resistance decreases.

In a parallel circuit, what happens to the current when it comes to a branch?

• The current stops.

• The current splits up.

• The current decreases.

• The current increases.
