A 2400 watt appliance operating at 10 amps has most nearly_____ ohms resistance.
E) need more info
I tried to find a formula to use, but i don't know which one to use. Thank you.
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.
so can i use P=i(^2)r
so the answer is A, correct?
