The image shows two types of circuits: series circuit (A) and parallel circuit (B).
In a series circuit, the current flowing through all appliances is the same. If one appliance burns, all appliances stop working.
In a parallel circuit, the voltage across all appliances is the same. If one appliance burns, the other appliances are not affected and continue to work.
In a common house, we need to plug and unplug appliances a lot of times, and each appliance needs to have a constant voltage across them.
That means Circuit B (parallel circuit) is the best circuit to be applied in houses/homes.
