How long has the NEC been charging for parking ?

Last time I went parking was free (2-3 years ago) but tomorrow, for the Classic car show, it's £16 (£12 in advance) . :shock:

I went to the motorhome show a few weeks ago and it was free parking?
The tube manual is quite like a telephone book. The number of it perfect. It is useful to make it possible to speak with a girl. But we can't see her beautiful face from the telephone number

A good day out was had, highlight of the day was seeing two Gordon Keebles.

As to the parking, it WAS £16 to get out of the car park.

A question for the knowledgeable

I'm having a senior moment, does the quiescent current (i.e. what you've set it at) of a power MOSFET decrease when it heats up?

I.e., opposite behaviour of a bipolar ...

No. Laterals tend to be stable with temp, but most other sorts of mosfet need temperature compensating if you want a constant current.

all mosfet and latfet datasheet will show the temp coeff graph. As Nick says latfets don't suffer variation like hexfets.

This is why it's wise to let mosfet amps settle for a good while before setting bias and offset if PP. This is particularly important if running high current bias with heatsinks.

to answer your question I believe current can vary up or down depending on temp and/or device....I think check the graph if you need to be precise.

Not been out on the bike then!

We didn't see any of the heavy snow the Met Office forecast mentioned for us - still bloomin' cold though!
Sorry, I couldn't resist!
