Okay it says here that i have a source voltage of 15v, i also have 3 resistors in parallel r1=470ohms r2=2.2kohms r3=3.3kohms, it asks what is the total current drawn from the source?
the answer says it is 43ma... i cannot come up with this answer and i do not know why...
any help?
in my book it says for parallel resistors to first convert the ohms to siemens because then you can add the siemens up like you do in series resistors. Then it says take the total siemens added up and then divide 1/ total siemens added up and you get the total resistance. well, that does not work for me and i do not know why
