Explanation:

Step1: Recall electrical - circuit principles

In a household electrical system, parallel - wiring is used to ensure that each receptacle and light socket has the same voltage. In a parallel circuit, the voltage across each branch is equal to the source voltage.

Step2: Draw a schematic

Draw a simple schematic with a voltage source (e.g., a utility - provided 120 V source), several light bulbs and receptacles connected in parallel. The voltage source is represented by two parallel lines of different lengths (longer line for positive and shorter for negative), and the light bulbs and receptacles are represented by their respective symbols connected to the two lines of the voltage source in parallel.

Step3: Explain the parallel - wiring advantage

When components are connected in parallel, the current divides among the branches according to the resistance of each branch, but the voltage across each component remains the same as the supply voltage. This ensures that all electrical devices in a house, whether it's a lamp or a power outlet, operate at the same 120 V (approximate in the US household system).

Answer:

The main wiring plan for houses to ensure that each receptacle and light socket has the same voltage is parallel - wiring. A schematic would show a voltage source with multiple light bulbs and receptacles connected in parallel to it.
