switch -on

Hi all back on night shift

The current to a tungsten-fileament lamp at the moment of switch on = is it is lower than the running current or significantl greater than after a second or so:Spam2

 

[Andy™]

think about the resistance when cold and when hot, and what would therefore happen with the current

^^ what he says

 

[revjames]

I would have thought the resistance of the element would be higher at the start then lower when it gets hot?

opposite...

 

[revjames]

yeh thats what I meant - ahem just testing

Is it a dimmer switch? trick question? :C

Here`s the "trick" bit of the question:

Is the O/P EVER going to attempt to answer summat; we`ve told him to (at least) TRY to answer gawd-knows-how-many-times.........but he doesn`t listen to us.....

The current to a tungsten-fileament lamp at the moment of switch on is = to the square root of the current on the hypotenuse!

Actually it may be higher if its a metal faceplate... cuz they are more conductive!

NO! it IS a trick question cuz they don't tell you which room this light switch is in!
