An ​ (a)   in the number of light bulbs will increase the ​ (b)   in a circuit. The flow of current will ​ (c)   , while the voltage will ​ (d)   .

• resistance
• decrease
• stay the same
• increase

What is a parallel circuit?

• A circuit where electric charges follow a single path

• A circuit where electric charges can follow multiple branches

• A circuit with no resistance

• A circuit that stops working if one branch breaks

What happens to the resistance of a parallel circuit when more branches are added?

• It increases

• It decreases

• It remains constant

• It fluctuates

What happens if there is a break in one branch of a parallel circuit?

• The entire circuit stops working

• The current can still flow through other branches

• The voltage increases

• The resistance decreases

Why does the current increase in a parallel circuit when more branches are added?

• Because the voltage increases

• Because there are more paths for electrons to follow

• Because the resistance increases

• Because the circuit becomes unstable
