Many electronics factories use machines that place the electronic components into the printed circuits.

What's the name of this technology?

i'm solving electronic homework ,and i got the values R1=66.67
R2=12.4k
(and Rs=10 ,RL=1k are given),there is part in the question which want me to chose the closet values for the resistor before i design the circuit in pspice program.
can u tell me how i can chose from the given appendix below

Preferred resistance values (approximately 10% increase)

I1.01.52.23.34.76.8
II1.11.62.43.65.17.5
III1.21.82.73.95.68.2
IV1.32.03.04.36.29.1

I to IV for (+-)5% tolerance resistors
I and III for (+-)10% tolerance resistors
I for (+-)20% tolerance resistors

Values multiplied by 1, 10, 100, 1k, 10k, 100k, 1M, 10M
Multiplier 10 to 100k can cover all the preferred values
E.g. 11, 110, 1.1k, 11k, 110k

Resistor types: Carbon film, metal film, wirewound
i think this will be clear

I(1.0)(1.5)(2.2)(3.3)(4.7)6.8)
II(1.1)(1.6)(2.4)(3.6)(5.1)(7.5)
III(1.2)(1.8)(2.7(3.9)(5.6)(8.2)
IV(1.3)(2.0)(3.0)(4.3)(6.2)(9.1)

How do electrical circuits make stuff work? Like i don't see how inducing a current on anythign can make it work… such as, how does an Xbox controller make the commands do stuff in game… things like that, idk i hope i conveyed my question well enough, but i am terribly confused

If you open any small digital multimeter or any small equipment which has a plastic cover, it has a small aluminum foil pasted on inside of the back cover and when you put the cover in place the foil touches a spring soldered on the PCB ( printed circuit board ) of the meter. Thus the foil is connected to the ground line of the PCB through a foil. What is the function of this arrangement?

i need to electronics circuits simulations software ,pls give me the name and download link. thanks..

I want to know how to fit a relay SRD-05VDC-SL-C on the circuit board. Which terminal goes where? There are 5 terminals on it and I can't figure out where to fit those on the board. Tried looking for the datasheet for info but to no avail…please help ASAP..tq

I’m not that interested in bigger electrical designs.. I want to start a career in electronic engineering, designing, testing, whatever.. everyday circuit boards or telecom. Would a BS in electrical engineering with a focus in electronics be good enough? and wouldn’t I have more job options with a BS in electrical engineering, or would I lose some job opportunities in the electronics field? I’m kind of young and married, so I need a career that will be stable, decent pay and enjoyable for me.
Thanks, but I want to know about the degree itself.. I'm strictly interested in electronics, not so much electrical.. Is an "Electrical Engingeering" degree with focus on electronics good enough to have a good Electronic Engineering career or would it be necessary for me to get an "Electronics Engineering" degree. Thanks again

This is a two part question….
I know there is a 12 step programs available for people who have substance abuse problems. Is there one available for fishing? I just can't seem to get enough of it. I even have dreams about it.
Part 2: Does anyone know how to go about getting on the pro or semi pro circuit fishing tournaments or working for anyone in this industry that makes tackle and needs a professional spokesman / salesman. I am in electronic tech sales now.

The parts have been accumulating there for years, complete with pieces of solder, various circuit boards and loose electronic components. Shouldn't it have evolved into some form of computer by now, complete with operating system?

Hmmm, maybe I need to throw some pure silicon on the pile and start adding additional heat. Would that work?

I wish to time the period of a cycle and then use the formula: 3600/period equals the cycles per hour. I asked a similar question earlier and miscategorized it.
The cycles per hour is a slow frequency. The formula is cylcles per hour = 3600/(seconds per period). Ex: 900 pieces per hour = (3600 seconds per hour)/(4 seconds per period).
