Hello, I've been accepted to university to both fields that I have chosen, but I can't decide, they both seem good. The subjects are - Electronics and bionics, Mechatronics. A little about my backround; I've graduated in industrial automatics, and know thing or two in programming and I...

it will work out transistor mechanism just fine. never said so.

you can look at transistor as two diodes facing each other --l>l-*-l<l--- this also forms NPN junction and will let thru if voltage is applied to the between. Your assumption is basically correct ~ Applying + to emmiter will draw free electrons from there leaving + ions, applying -...

Oh well, it would be pain in the *** honestly, It does not matter what battery you use, it will run out pretty fast, so you would need to buy them every day, it's just the higher the voltage, the faster heating element will heat up. Thermistor would definitely work for fast heat up, but your...

You need wire with high resistance, or you could also put resistors in parallel circut. What do you want to do with such wire? Nichrome V is one of wires that has high resistance.

Here's image so you don't have to dl itBy the way, Lm represents electromagnetic field http://img135.imageshack.us/img135/308/inductor.png Uploaded with ImageShack.us

I'm having hard time understanding how exactly current that passes through inductor transforms energy into magnetic field and then into voltage, with 90° phase shift. I drew schemes representing sinusoidal imput current, its magnetic field and voltage relation. Is it correct? Would...

E is energy or Joule in other words?

Thanks guys, that made things a bit clear. Yeah I have heard it too, that it's like if there's pipe filled with water and you add, say, 1 litre to one end, you will also get 1 litre out of the other end, but if there's load or resistance, the energy that was added will be absorbed by...

I found awesome channel that explains all that stuff, you'd be better off listening to this guy than me - http://www.youtube.com/watch?v=3BYXuYybaNg&feature=channel_video_title There are many videos on his channel about different stuff.

Hello, I'm bit confused about relation of the two, would be really great if someone explained it. So the coulumb is said to be the force between two charges(repelling or attracting), which depends on quantity of charges and their distance. Joule is said to be force that is needed to move...

Yes it will, it's called generator. It will give out electrical energy if you will use mechanical energy by rotating the coil, and will rotate by giving electrical energy, which is electrical motor. But it has to be done correctly to work so: You must have coil in between of two magnets, so...
