controlling light bulbs in series setup
controlling light bulbs in series setup
(OP)
hi everyone
was wondering how you can individually control two light bulbs in a series circuit
the scenario would be something like you have a single power source and two bulbs, one red one green, and two switches.
i know there is an easy way to do this using a parallel arrangement but is there a way to design a series setup(i.e. the bulbs are connected in series, switches also in series, in one loop) that would allow you to individually control the two bulbs? ok to include use of other parts like capacitors and diodes important part is that each switch should exclusively control one bulb.
thanks for any help you can provide

RE: controlling light bulbs in series setup
The simple one:
A Use AC. If your bulbs are 110 V, use 220 V.
B Put a diode across each lamp. One diode pointing from the switches and one diode pointing to the switches.
C Put two switches in series. Put a diode across each switch. One diode pointing to the lamps and one diode in the opposite direction.
D Test.
E Bet someone that it can be done.

Sounds like the kind of trick puzzle people dream up late after having had one too many.
Like the one about finding out which lightbulb belongs to which switch when the switches are downstairs and the bulbs are in the attic......
Yes, it's possible.
Benta.

But neat solution. Isn't that how run-way lights in air fields are connected?

Can't speak to the airfields, but series-connected lighting with a voltage:current transformer was a common early method of street lighting. Most of that stuff has been ripped out by now though
