Detailed explanation-1: -Wires are used for establishing electrical conductivity between two devices of an electrical circuit. They possess negligible resistance to the passage of current. The wires are covered by an insulated coating of different colours.
Detailed explanation-2: -Conductive wires or traces are used to connect the components to each other. However, a circuit is complete only if it starts and ends at the same point, forming a loop.
Detailed explanation-3: -To recap, the hot wire carries electricity into a component. The neutral wire returns electricity from the last component to the power source.
Detailed explanation-4: -In a series circuit, all components are connected end-to-end to form a single path for current flow. In a parallel circuit, all components are connected across each other with exactly two electrically common nodes with the same voltage across each component.
Detailed explanation-5: -Connecting wires in a circuit are assumed to have zero resistance unless otherwise stated. Wires in a circuit can be shortened or lengthened without impacting the circuit’s function-all that matters is that the components are attached to one another in the same sequence.
