Discussion Overview

The discussion revolves around the electrical connection of six light bulbs in a hanging lamp, specifically whether they should be connected in series or parallel. The context includes theoretical reasoning and practical implications related to household wiring and electrical principles.

Discussion Character

  • Homework-related
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • One participant suggests that the bulbs are likely connected in parallel to ensure each receives the same amount of current.
  • Another participant explains that in a series connection, the current would pass through all bulbs sequentially, while in parallel, each bulb would have the full voltage applied to it.
  • A later reply emphasizes that traditional wiring for 120V light bulbs is in parallel, questioning why one would not connect all bulbs in series.
  • One participant notes that a key factor in series connections involves an additive property of each load on the system.
  • Another participant outlines two reasons for connecting bulbs in parallel: maintaining a constant voltage across each bulb and preventing all bulbs from going out if one fails.
  • A humorous comment is made regarding the terminology used, referring to "lambs" instead of "lamps," adding a light-hearted tone to the discussion.

Areas of Agreement / Disagreement

Participants generally agree that connecting the bulbs in parallel is the traditional and preferred method, but there is no consensus on the implications of series versus parallel connections, as some points remain contested or unclear.

Contextual Notes

Some assumptions about electrical principles and household wiring practices are present, but specific mathematical or technical details regarding the calculations or effects of series versus parallel connections are not fully explored.

I know that this is going to sound like a stupid question, but I was wondering if someone could explain the reasoning behind this question.

A hanging lamp illuminates a banquet table using 6 light bulbs (120 V). How are the bulbs connected? Series or parallel?

Any help would be great.

I think that it would be parallel so that each light receives the same amount of current, but I am not really sure.
 
If they are in series that well each receive the same amount of current since they the current will pass through only one path, that includes all of the bulbs. However, in parallel, each bulb will have the full voltage from the source applied to it.

The traditional way that 120V light bulbs are wired is in parallel. Quiz question for the original poster (the OP, dmolson) -- why would you not want to connect all the light bulbs in your house in series?
 
A key factor in a series connection would have to do with a certain additive property of each load on the system.
 
Dmolson, normally any combination of lambs would be connected in parallel, there are two reasons for this:
first, the outlet of your home gives a constant 120V with varying current (depending on the load), so when you connect several lambs in parallel, you will have a constant voltage drop on all of them and they can take as much current as they want (there is a limit!), while if you connected them in series, the voltage across the lambs will be divided among them, while having constant current which is not what we wnat, the second reason is that if you connect lambs in series, if one of them goes out, the one's following this lamb will go out too.
 
Electrified lambs are not, to the best of my knowledge, either tasty OR safely cooked... And it's kind of cruel and unusual to the lamb, isn't it! :biggrin:
