Can you help me identify these components and values?

    Hello all,

    I recently acquired a bundle of electronic components. I have a lot of capacitors but don't know how to tell what there capacitance is? Could someone tell me how to find out or point me in the right direction please?

    The first one has the following printed on it: 680k100

    the second: 22k400

    And also I have a lot of these:

    Your pictures are very unclear. But I could see enough to guess. If a guess would help you I will give it a shot.

    The first two orange plastic devices are probably capacitors. I would suggest buying a multimeter with a capacitance checker. I will tell you that I think the 100 and 400 trailing numbers are their voltage rating.

    The third picture looks like a crystal, normally used for selecting Radio range or intermediate frequencies.

    The 4rth picture looks like a photoresistor but it is way too blurry to have any clear idea.

    I won't tell you what the capacitors are because I think I could be off by a factor of 1000.

    Ahh I see, I'l see if I can buy a capacitance meter in a few days, looks like I'm going to need one! I'l take some more pics tomorrow, I didnt realise how bad those pics were!

    Thanks!

    I actually looked at the pictures again and I think the multimeter shown in the background has a capacitance feature.

    680K100 = 680nF K=10% of tolerance, and 100 = 100V
    22k400 -->22nF 10% 400V

    Yeah it does but it doesn't show anything? Seems to only work with electrolyte capacitors.
