9.1 Parallel Circuits

What is a characteristic of a series circuit?

• Multiple paths for current flow

• Only one path for current flow

• Current is divided between components

• Current varies at different points

In a series circuit, if one component stops working, what happens to the rest?

• They continue working

• They receive more current

• They also stop working

• They work at reduced power

What happens when the switch in a series circuit is opened?

• The current continues to flow

• The circuit is broken, and all components stop working

• The current increases

• Only one component stops working

How does current behave in a series circuit?

• It decreases at each component

• It is different at different points

• It is the same throughout the circuit

• It depends on the number of components

Why can’t a lamp and buzzer be operated separately in a series circuit?

• They share the same voltage

• They are in the same path of current flow

• The circuit is too complex

• The switch only controls one component

What is a characteristic of a parallel circuit?

• Only one path for current flow

• Multiple branches for current flow

• The same current in all branches

• The current stops if one component fails

What happens to current at a branch in a parallel circuit?

• It stops flowing

• It remains the same

• It is divided between the branches

• It only flows in one branch

In a parallel circuit, what happens when one component stops working?

• The other components continue working

• The whole circuit stops working

• The voltage increases

• The current stops

What does the total current in a parallel circuit equal?

• The highest current in a branch

• The sum of the currents in all branches

• The lowest current in a branch

• The difference between branch currents

If a parallel circuit has three branches with currents 1.0A, 2.0A, and 0.5A, what is the total current?

• 1.5 A

• 3.5 A

• 2.0 A

• 4.0 A
