Final answer:
True, house wiring typically employs parallel circuits to ensure each appliance receives consistent voltage from power lines, allowing for independent operation of each device. Some household systems use a combination of series and parallel circuits for efficient functioning.
Step-by-step explanation:
True, a common application of parallel circuits is indeed typical house wiring to the power line. This configuration is used to ensure that each appliance in the house gets the same voltage as all others. In a parallel circuit, devices such as lights, outlets, and appliances are connected in such a way that the voltage from power lines is distributed evenly across them. In contrast to series circuits, where the voltage would be divided among devices, parallel circuits allow for consistent voltage levels across all devices. This is crucial since most home appliances and electronics are designed to run on a specific voltage. Moreover, it allows for each appliance to operate independently, so if one appliance fails, it does not affect the operation of the others.
Considering electric circuits in a home, two examples that require a combination of series and parallel circuits are the wiring of multiple light fixtures on a single switch (parallel) combined with series connections within each fixture (e.g., light bulbs in series), and the combination of a central heating system with individual thermostat-controlled zones (parallel) with the series elements in components like pumps and valves. It’s essential for the efficient operation of complex systems such as these.
