hi ive been having bit of trouble lately on how to find or measure how much mA i should feed the circuit i managed to find the current that travels through the resistors, can some1 show how to determine the mA that goes through a laser ive been using ohms law I=V/R but i still am having trouble

i am plannin to use 6 0r 9 volts i have 2 10ohm resistors in parrallel

So . .

I=V/R

I=9/5

then i get 1.8A?

this is were i get stuck, at the symbol
