An alarm clock is plugged into a 120 volt outlet and has a resistance of 15,000 ohms. How much power does it use?

The power used is 0.96 watts.

Explanation:

Recall the formula for electric power (P) as the product of the voltage applied  times the circulating current:

and recall as well that the circulating current can be obtained via Ohm's Law as the quotient of the voltage applied divided the resistance:

Then we can re-write the power expression as:

which in our case becomes:

i'm thinking more like energy

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!
