A small question to aid me in my hobbying...

Did anyone do some basic electronics at school/uni?

I've got a 25W, 240V AC halogen bulb (G9 fitting, although that's not
important apart from the fact it's impossible to get a basic holder for it
that's not part of a fancy light) that I'm using as part of a model I'm
building, and the fact that it's 240V AC suggested to me I could just wire
it straight up to the mains. However, when I did so, it shone for about a
second before blowing.

It's been suggested that I need to put a resistor in series with it, to
limit the power flow to 25W? If that's right, how big a resistor do I need?
Or did I just get a duff bulb?

Thanks _ brain,

Oliver.
