The electrical circuit when turned on it is considered closed. By the same token when an electrical circuit is turned off the electrical circuit is considered open.
Electrical devices need an electrical circuit.
The carbon allotrope we call diamond has the highest thermal (heat) conductivity of any material. It is far better an any metal (or anything else we know of) at allowing heat to pass through it. It is carbon (in its graphite allotrope) that has the highest electrical conductivity under normal conditions of any of the nonmetals. Any metal is a better electrical conductor, but carbon is good enough to make brushes for electrical motors out of. You'll recall that the brushes complete the electrical circuit between the wiring of the non-moving elements to the rotating commutator.
Water is neither an open or closed circuit. There is no electrical circuit without a power supply and a load. With that said, pure water is not a good conductor of electricity; if other matter/ions are present in the water, the conductivity may be high enough to consider it a good conductor.
Then the brightness of the light buld increases.
I don’t know
wires that have got good conductivity and less losses

Current increases if the voltage remains constant.
Electrical properties of non-ferrous material 1. It provides low resistance to the circuit. 2.conductivity of electrons(current) is better. 3.
The electrical circuit when turned on it is considered closed. By the same token when an electrical circuit is turned off the electrical circuit is considered open.

Copper is not a good insulating material for either thermal or electrical conductivity. Copper is actually a very good conductor of both heat and electric current, hence its use in electrical wiring, circuit pathways, and heatsinks.
Increases the total resistance
