• ### Can someone simply explain this question I have about the Ohm's Law formula?

I learned that Current is proportional (corresponding in size) to Voltage (if Resistance remains the same of course). I also learned that Current is inversely proportional or the opposite to Resistance (if Voltage remains the same). I don't understand why we would use V = I x R. Why are we multiplying the... show more
I learned that Current is proportional (corresponding in size) to Voltage (if Resistance remains the same of course). I also learned that Current is inversely proportional or the opposite to Resistance (if Voltage remains the same). I don't understand why we would use V = I x R. Why are we multiplying the amps by resistance to get voltage? I also don't understand why we would divide I = V/R to get Amps and R = V/I to get Resistance. Why would be divide if the voltage and amps are proportional?

• ### 3 one phase the same as 1 three phase?

Best answer: 3 phase systems can be broken down into 3 single phase systems - and indeed they mostly are - but three arbitrary single phases can't be combined into standard three phase system. They could only be combined into such a system if they are synchronous, have 120 degree phase shifts and a common ground.

• ### Hey! What is the best public college in the USA to study Aerospace Engineering?

Best answer: MIT is the WRONG answer, as it's a private institution. So are Caltech, Stanford, and Carnegie-Mellon.

Top public universities in this field would be Georgia Tech, U of Michigan, and Purdue.

• ### How would concentrated electricity affect electronics and vehicles when used as a power source?

The very idea of concentrated electricity came from watching an episode of Phinas & Ferb while they were pumping air into a giant bounce house, and they mentioned the air being concentrated inside of it.

The very idea of concentrated electricity came from watching an episode of Phinas & Ferb while they were pumping air into a giant bounce house, and they mentioned the air being concentrated inside of it. Now, I know I'm always asking these questions. But I ask them because I'm trying to bring about abundant energy for all, so that we will create a highly-advanced technological society faster, like you see in most contemporary science fiction films and stories. If it is at all possible to safely concentrate electricity and intergrate it into technology without destroying the machines and electronics, how efficient would the concentrated electricity be as a fuel or power source?

• ### How to discribe a machine's heat dissipation is good? which phrase can be used?

PLS help me~ I want to discribe a machine's(e.g a LED lamp) heat dissipation is good, which phrase can I use? I can think of some phrases but usure if they are authentic: " premium cooling"? " excellent heat dissipation"? I prefer a 2-word phrase. Thanks a lot!!!

• ### How to make an electric circuit that lights two lights individually, and both at the same time using a master switch? I have 3 switches?

Best answer: VERY SIMPLE TO DO IT WITH 3 SWITCHES YOU HAVE....... [1] Connect first switch in series with one bulb. [2] Connect second switch in series with another bulb. [3] Parallel both circuits, then add the third switch in series between power source and this parallel path. [4] Turn one switch ON as you wish to light up... show more
Best answer: VERY SIMPLE TO DO IT WITH 3 SWITCHES YOU HAVE.......
[1] Connect first switch in series with one bulb.
[2] Connect second switch in series with another bulb.
[3] Parallel both circuits, then add the third switch in series between power source and this parallel path.
[4] Turn one switch ON as you wish to light up just one bulb. Turn two switches on to light up two bulbs.
[5] The third switch is the master switch allowing power go through the circuit, a master ON-OFF switch.

• ### What force are you trying to move up the stairs when you walk/run up it?

We are doing a lab where we walk up stairs and then run upstairs and then try to find the work and power done for each one. I don't really get this question though, what force?? We're not trying to move a force, we're moving ourselves, or maybe I'm completely missing the point.

• ### Power supply output voltage is different than rated?

Im having a problem here. I bought a power supply 5 months a go and i did not check the output voltage. I only check it 5 months later. The rated output voltage is 12V and 20A But what i measured using multimeter is 6V. I dont know if the component inside is broken or something. Please help.

Best answer: "4V dissipated across it" NO, it has 4 volts across it. parallel components all have the same voltage, and the battery and the 2 resistors are all in parallel. voltage is not "dissipated", it is a potential difference.

Best answer: "4V dissipated across it" NO, it has 4 volts across it.

parallel components all have the same voltage, and the battery and the 2 resistors are all in parallel.

voltage is not "dissipated", it is a potential difference. Think of three bricks on a shelf 1 meter off the ground. All three bricks have the same gravitational potential.

Current, on the other hand, divides. Each R has 1 amp of current THROUGH it, and the battery has to supply 2 amps.

Power, is DISSIPATED. Each resistor dissipates 4x1 = 4 watts, and total power is 8 watts, and the battery has to supply that 8 watts.
