(maybe this is why I'm not an EE major) but if you are supplying the 7805 with power from a DC power supply, how can the 7805 only have voltage as an input when the dc power supply has both a voltage and current output?
I guess for the current question i should have rephrased it. I need the regulator to output one amp, would I be safe putting more than one amp to the input of the regulator?
I have a couple more questions. is it absolutely necessary to have the two capacitors in the circuit
"*Required if regulator input is more than 4 inches from input filter capacitor
(or if no input filter capacitor is used). <- ON INPUT
**Optional for improved transient response." <-ON...
yes I know, but you did not read my question. my question was how does heat impact its performance, I know the hotter the chip is the lower the current output will be. do I need to worry about a heatsink on it at all? according to this at 25 degrees Celsius, it will output 1 amp (...
after doing some more research I found out I need about 900mA to 1 amp. will the 7805 guarantee putting out that much? and should I put a heatsink on it to help (and how)?
I was going to use a +5V Fixed-Voltage Regulator 7805, for a project until I noticed that I need 2 amps and the 7805 can supply at max 1 amp. what can I do?
i really don't know where to start with this problem
Consider the setup of a single slit experiment
The first minimum for 440 nm light is at y1.
The first minimum for 529 nm light is at y2.
what is the ratio of y2/y1?
i know that the distance between two max is
(wavelength*dis...
the book I'm currently using is Fundamentals of physics 7th edition by halliday resnick and walker. and i just don't like the book and haven't liked the book for the previous 3 physics classes that i have taken.
heres a course description of the classes that i could use book sugestions for...
