Electrical circuits are usually designed by the electrician in the construction of both closed and open (e.g. parallel) circuits.
A closed circuit can be defined as an electrical device where energy only flows through it, while a parallel circuit is where different lines are connected together, thereby diving intensity.
In conclusion, electrical circuits are usually designed by the electrician in the construction of both closed and open (e.g. parallel) circuits.
