Max current for Cds photocell ? [and temp-drift Question

[petemoore]

  I'm driving a solenoid coil with V+, LDR, Relay, Gnd.
 Change the state of light on the LDR and the Relay changes state.
 Will the LDR not like passing current like this [rated 50v iirc, I'm probably running <20ma.] ?
 What are the heat related characteristics of the R values of Light/Dark ?
 ie when ~1k [or lowest R] the current will be highest, will this cause eventual failure or 'excessive' drifting ?
  Mod: Whoops this relay says 24v 5a [doesn't seem right though] and tested operative on 9vdc.
  Perhaps there's a relay part which does good work @ 9vdc, is a dpdt and is recommendable for bypass applications?

I'm a little confused; you're putting the LDR in SERIES with the relay coil?

I think you'd be better off using transistor switching of some description mate!

This should work:

  Now we're both confused.
  Yup..Battery>Photocell>Relay>Circuit.
  Not sure what the transistor deal'd be...emitter follower or something ?
  Workin' on that too anyway as it turns out, see thread about Photocell to light LED when LDR is dark.
  If I can get that going I can probably get the relay going..it'll all get going I'm just lazy about twistin' parts together then untwistin' em again and again, figured I'd put leads out and study it some more.
