    Use OHMs law: E= IxR. E is voltage, I is current (amperes) and R is resistance (OHMs). I'll forgive you if you never took Algebra 1. E=9, R=10 and you want to calculate I. I would come out to 9/10..... nine tenths of an ampere, since E/R=I.

    Theoretically, 900 mA.  I = E/R. P = I x E. 

    Depends on size of  conductors, A/Hr rating of battery. And, if resistor can safely dissipate 8.1 watts. It should be rated at 12 watts for safety. Wires need  to be  #24 AWG  or bigger and very short so  they don't drop too much voltage. 

    U can detonate an electric blasting cap, Once, w/a 9 volt alkaline. These  require 2 volts at one amp,  suddenly, not a gradual rise in current.

    I'll explain it to you the way it was explained to me. 

    Elmer has two girlfriends, Iris and Rose. 

    When Rose is away, Elmer is over Iris.  R = E/I. 

    When Iris is away, Elmer is over Rose.  I = E/R. 

    And when Elmer is away, the girls get together.  E = I*R.

    That's how it was taught back in the day.

      You're an old guy, I had an instructor that got fired back in the 80's for teaching us- Bad Boys Rape Our Young Girls But Violet Goes Willingly - resistor code memory tool

    What current flows through a 10 ohm load at 9 volts?

    E/R = I

    9/10 = .9 amps

    V = IR

    I = V/R

    I = 9/10 = .9 Amp
