  1. This is funny,
    A will turn on with the switch
    I, N, and G will light continuously

Not sure that was what the author thought he was doing, lol.

None as the picture is

If the switch is closed then only A will light.

M & P are not connected to negative so no light

K is only connected to negative so no light

I N & G are connected to a set of batteries with only the positive terminal so no light.

Because will all need good batteries.


Hey @jhmiller, Look at the diagram again. This is where I think the author did something he or she didn’t intend to. I agree with you in that I believe the author wanted to show no connection from the negative side of the battery set but the connection is made to the negative side of the previous battery in the row via the connecting wire between the two batteries. The last or first battery in the row (perspective) does nothing.


I have no use for these batteries, so I’m not going to participate…
The question is, which bulbs can be lighted up?
So technically speaking, without changing anything in this diagram only A can be.

I, N, G are constantly lighted due to the lack of a switch. You can’t light what’s already lighted, right? :slight_smile: You could disconnect the lower batteries and reconnect them but that way you’re changing the diagram.

Look again my friend! :wink:
The artwork is deceptive…


agreed that 6 of the 7 in bottom row are connected in series but how they are wired is blocking every bulb from getting both poles connected to the source, right??lol, idk, whatever
