Read each question carefully and answer to the best of your ability. Show all your work for calculation problems.
Study the diagram of the parallel circuit below:
1. In a parallel circuit, if one component breaks, the other components will functioning.
2. The voltage across each branch in a parallel circuit is .
3. The total current in a parallel circuit is the of the currents in each branch.
4. Which of the following is an advantage of a parallel circuit over a series circuit?
It uses less wire.
All components share the same current.
Adding more components increases total resistance.
Components can be operated independently.
5. In a parallel circuit, the total resistance is always greater than the resistance of any single branch.
True
False
6. Explain why household electrical wiring is typically configured as a parallel circuit rather than a series circuit.
