Read each question carefully and answer to the best of your ability. Refer to the diagram of the parallel circuit to help you with some questions.
Observe the diagram of a parallel circuit below:
1. In a parallel circuit, if one component breaks or is removed, what happens to the other components?
They all stop working.
They continue to work.
They work intermittently.
Their brightness increases.
2. What is constant across all branches in a parallel circuit?
Current
Resistance
Voltage
Power
1. In a parallel circuit, there are multiple for the current to flow.
2. Adding more resistors in parallel will the total resistance of the circuit.
3. Household electrical wiring is typically arranged in circuits.
1. All components in a parallel circuit share the same amount of current.
True
False
2. If one light bulb in a parallel circuit burns out, the others will go out as well.
True
False
1. Explain one advantage of using a parallel circuit over a series circuit in a household electrical system.
2. Describe how the total current in a parallel circuit is related to the current in its individual branches.
