its a series connection
A 240 volt street light circuit is wired in parallel connections. In the base of the street fixture an inline fuse is connected into the circuit that goes up to the fixture to protect the lamp head.
A: Adding any resistance bulbs or whatever in a series circuit will reduce current and will reduce total power. In this case the bulb will glow dimmer as any additional bulbs are placed in the series circuit. this is true if the same input source is kept constant.
There are many types of electrical circuits and each one is wired differently. Without knowing the specific circuit that needs to be wired, this question can not be answered.
It is not the number of bulbs that you worry about. It is the wire size that is your concern. If the circuit is wired with AWG 12/2 wire then use a 20 amp breaker. If it is wired with a AWG 14/2 wire then use a 15 amp breaker. You are protecting the wiring with the correct size breaker.
That would be a parallel circuit.
That would be a parallel circuit.
That would be a parallel circuit.
Since the SAME electrons have to go through both light bulbs, the current in both light bulbs will be the same (Kirchhoff's current law).
The two bulbs will be wired in parallel with each other. The switch will be wired into the circuit upstream of the bulbs.
the circuit must be wired in parallel.
The question is ambiguous, however one possibility is a parallel circuit, which would permit one light bulb to remain lit while the other light bulb was switched off. By contrast, if the light bulbs were connected in a series circuit, switching one light bulb off would cause both lights to go off.
reduces it from 1/2 to 1/3rd
If a circuit is wired in parallel, all the bulbs have their own independent access to electricity, so if one bulb goes out, the others are not affected. If the circuit is wired in series, then one bulb going out will block the current to all the other bulbs as well.
Can't answer that w/o knowing the Ampere rating of the fuse. A standard house circuit being 15 amps you would load the circuit up to 14.7 amps with 27 light bulbs.
I you wired a light bulb in to the same circuit you have the possibility of over loading the circuit but other than that it would just be brighter.
As a series circuit, as asked, all bulbs will go off because of that just one bulb.
