A 2400 watt appliance operating at 10 amps has most nearly_____ ohms resistance.

A) 24
B) 0.5
C) 5
D) 240
E) need more info

I tried to find a formula to use, but i don't know which one to use. Thank you.

  • PHY (NEED ANSWER SOON PLS) - ,

    Power = Vi = V²/r = i²r
    In the given problem, you have been given the current i=10 amps, Power = 2400 watts.
    The resistance can be calculated from one of the above formulas.

  • PHY (NEED ANSWER SOON PLS) - ,

    so can i use P=i(^2)r
    r=P/i(^2)=24

    so the answer is A, correct?

    Right!
