My first post. Hello all, glad to have found this site!
I have just started first year at college for Electronics Engineering. I get Ohms law, eg; if I have voltage and Ohms I can figure out Amps, etc.
If I am asked to calculate total current in a circuit being supplied by a source with 10V /.20A going across a circuit with 3.8kΩ of resistance and am then asked to calculate total current, would current just be the same as supplied from the source (.20A)? I am confused...
If I try to calculate current by dividing source voltage 10V by 3.8kΩ to get current, I dont arrive back at the source supplied current of .20A, instead I get 2.632mA .
I am missing something here and have puzzled over it for awhile now and cant figure it out. I checked the forums but wasnt sure what search terms to use to find the answer to this specific question.
