I have a circuit board I am trying to redesign but there are three SMT parts that have NO markings on them. They are extremely small and I used a magnifier to take them off and look for a PN or something. There are NO destinguishing marks on them. They all have two contacts so I figure they are either a resistor, a diode, or a capacitor. Does anyone have any idea on how I could test the to see what they are and what there values are.

Thanks

I am using a 2n3055 NPN transistor as a switch gate. The base is supplied via a signal gnerator. One moment, it was working fine and then... all went silent. How can I tell if it is the fault of the transistor?

Is this possible according to the laws of physics, and if I did manage to do it, would it be a worthwhile invention, with potential?

Ok, so we have a little machine completely enclosed in a box, and the whole thing is on wheels. This machine has no external moving parts and does not need to interact with anything outside its enclosure to operate. This vehicle(since it's on wheels) can also propel itself about as fast as a turtle.

Is this possible, and is it something useful?

Sorry in advance for the extensiveness of this question...I just have a lot of concerns and I'm trying to voice them accurately... So, I love the idea of a liberal arts education-like at colleges such as Williams, Amherst, Middlebury, Bowdoin, but there's one itsy bitsy problem: none of them offer chemical engineering. I plan to study abroad and also study romance languages so liberal arts colleges appeal to me. The liberal arts colleges offer chemistry though. Is it possible to get a B.S. or B.A. in chemistry from a prestigious liberal arts and then attain a major in chemical engineering from a different reputable school? Will a prestigious graduate school such as yale accept me from a liberal arts? Can I still hope to pursue chemical engineering if I go to a liberal arts school?!

A copper RTD is used. Its resistance at 32F is 100 ohms, and its temperature coefficient is 0.245 ohm/F. What is the ohms at 200F?

Please provide an equation instead of RTD table.

(only using differentiation)
1) how fast is distance changing after 1/2hr (ans. 500mph)
2) how fast is distance between object and radar changing when object passes directly above the radar. (ans. 0)
3) suppose that line through the radar and object make an angle Θ with horizontal. how fast is Θ changing 10min after object passes over radar. (need help with this one)

give hints and ans for 3 part

I need a measuring device not too expensive which I can use at home. I need a measuring device which measure distance by reflection of light and tell me the distance digitally. I don't want to use a meter tape. I need at least a device which measure at least a distance of 10m to 20m. Its like a do it your own tool.
