Final answer:
In a parallel circuit, if one load breaks or goes missing, the rest of the loads continue to work normally, as each load operates independently from the others. This is typical in household wiring and in vehicles, where each device utilizes the full voltage of the source.
Step-by-step explanation:
In a parallel circuit, if one load is broken or missing, the other loads in the circuit remain unaffected and continue to operate normally. This is because in a parallel circuit, each resistor (or load) draws the same current it would draw if it were connected directly to the voltage source.
For instance, in your house, devices like lights and appliances are usually wired in parallel so that they can operate independently. If one appliance stops working, it does not prevent the other devices from functioning. Similarly, in an automobile, the headlights, radio, and other electrical components are connected in parallel to ensure they utilize the full voltage and can function independently.
Headlights, radios, and other similar loads in a vehicle would continue to operate at full effectiveness, even if another component in the parallel circuit failed. However, if too many loads are connected in parallel, such as connecting an excessive number of 12-V lights to a car battery, this could result in dim lights due to voltage reduction from overload.
