• They continue working normally

• The current in the whole circuit stops

• The voltage in the whole circuit increases

In a parallel circuit, the total current is...

• The sum of the currents in each branch

• Equal to the voltage of the battery

• Always decreasing

What happens to the total resistance when more resistors are added in parallel?

• It increases

• It doubles

• It stays the same

• It decreases
